I. Some Terminology: Assignment Groups vs. Assignments, & How They Relate to Gradebook Columns

There are two common sources of confusion in understanding and using Canvas assignments and gradebooks. One is the distinction between Assignment Groups and Assignments. Assignment Groups are categories of assignments, such as problem sets, papers, quizzes, exams, presentations, and participation. They are important for organizational purposes and particularly important if you want to weight grades. Assignments are individual assessment items that receive grades, as, for example, first paper, second paper, or final paper. Assignment Groups and assignments are created separately. You can move assignments into different Assignment Groups by dragging them on the Assignment Index page or editing the Assignment.

Assignment groups vs Assignments

A second common source of confusion is how to create gradebook columns. In Canvas, assignments are tightly integrated with the Gradebook and the only way to create a gradebook column is to create and publish an assignment . This may seem unintuitive at first glance, as not all assignments require online submissions (e.g. attendance and participation or assignments done on paper). However, instructors can choose different submission types when they create an assignment— No Submission, Online, or On Paper . The one-to-one correspondence between the number of assignment items and the number of gradebook columns ensures that grading policy is transparent to the students and that both instructors and students always see the same number of assessment items.

II. Weighting Grades

You can have Canvas automatically calculate weighted grades in just a few clicks: on the Assignment Index page, click Options , select Assignment Group Weight , then enter the percentages for each Assignment Group. For example, in a course where the grades are determined as follows:

The process for weighting grades is:

To weight grades, go the the Assignments page, click on the Options button, select Assignment Groups Weight , select the Weight final grades based on assignment groups check box, enter the weights, and click Save .

How Canvas Calculates Weighted Grades for an Assignment Group

Canvas determines weighted grades by calculating:

• the grade (in percentage) of individual Assignment Groups (sum of points scored divided by total possible points);
• the total grade (sum of Assignment Group grades multiplied by their respective weights).

In the example for “Paper Assignments” Group above, there are 4 assignments, each worth 20 points; together they add up to 80 points. The Assignment group counts 30% towards the total grade. If a student scores 18, 16, 10, and 15 respectively, then

The subtotal grade for “Paper Assignment” is: (18 + 16 + 10 + 15)/80*100% = 73.75% The contribution of “Paper Assignment” to the Total grade is: 73.75% * 0.3 = 22.13%

Weighted Grades within an Assignment Group

In the above example, because each assignment has the same maximum points (20 points), each assignment contributes equally within the Assignment Group. If you wish a particular assignment to weigh more, just make sure it has a higher number of total points, or assign it to a separate Assignment Group.

Tips : If you have many assignments (about 10 or more) in one Assignment Group, and the total points for each assignment vary by one or two points, then by arithmetic the assignments contribute essentially equally to the Assignment Group grades, as the difference between each assignment after multiplying by the weighted percentage would be relatively small. (e.g. 1 point in an Assignment Group with a total of 100 points and which counts as 30% of the total grade is 0.3 points of the total grade.)

How Weighted Grades Appear in the Gradebook

In the Canvas Gradebook, each gradebook column (with linked heading) shows the raw points for an assignment (unless you have applied grade curving to it); the Assignment Group column (with black heading) shows the percentage a student scored for that Assignment Group; and the Total column shows the final, weighted grade.

In the example above, the Assignment Group column for “Paper Assignment (30.00% of grade)” is 73.75%.

NB : If a student didn’t submit a particular assignment, be sure to give it zero points. If you leave the score blank ( – ), Canvas will treat it as excused and ignore it in its calculation of the Assignment Group subtotal and Total scores.

For more about weighting grades, see: https://community.canvaslms.com/docs/DOC-10059-415267002

III. Muting Grade Notifications

When instructors enter grades into Canvas’ gradebook, a notification is sent to the student automatically . Some students are prone to panic if they find that their peers have received their grades but they have not. You can release grades to all students simultaneously if you select Mute Assignment and stop notifications from going out until you “unmute” the assignment. Muting assignments allows you time to review and make grade adjustments without sending students multiple notifications.

To mute an assignment, go to Grades, click on the options dropdown for the assignment, and select Mute Assignment:

Mute Assignment link in Canvas Gradebook

NB : Canvas does not include muted assignments in the Assignment Group and Total grade calculations—if it did, students would be able to calculate backwards and figure out what their grades are. Be sure to unmute assignments when you have finished grading them so that the gradebook calculations are correct.

For more about muting assignments, see: https://community.canvaslms.com/docs/DOC-12961-4152724339

IV. Grade History – Who Changed The Grade When?

From time to time you may wish to track how a student’s grade for a particular assignment changes over time, especially when there are multiple instructors or TAs giving grades in a course. Canvas’ Grade History tool can be helpful in such cases.

To access Grade History, click on the Options (gear) icon in Grades and select View Gradebook History . (In the New Gradebook, select the Gradebook dropdown, then “Gradebook History…”.)

To view grade history in the old Gradebook, select View Gradebook History from the gear icon on the Grades page, enter filter parameters and click the Filter button.

How to read Gradebook History

• The Before column shows the grade before the change at a particular date and time (row).
• The After column shows the grade after the change at a particular date and time (row).
• The Current column always shows the latest grade; it is the grade a student has now.

Example of Grade History

In the example above, on Jun 27, 2018 at 4:25pm, the Before column is empty because it is the first time a grade (0/20) is entered. On Aug 16, 2018, this grade is changed from 0/20 to 20/20. The Current grade for all rows is 16/20 because on Aug 17, 2018, the last time this grade was edited, the grade has been changed from 20/20 to 16/20.

NB : The dropdown selection can take a few seconds to display, especially if there are many students in a course. Be sure to click the maroon Filter button at the end to filter the results. You can filter for more than one category; for example, you can filter for student name and assignment name simultaneously.

V. Using Grading Schemes

You can apply a specific grading scheme to your assignment and/or overall course grade so that each letter or performance grade corresponds to a specific numeric grade range (e.g. A/Excellent = 91% to 100%; A-/Good = 88%-90%; etc). Once you have created a grading scheme, it can be reused in other courses you teach with just a few clicks.

Select Grading Scheme for an Assignment

To display letter grade for an assignment, edit the assignment, choose Letter Grade under the Display Grade as dropdown menu.

• Choose the appropriate grading scheme (see “Choose/Create New Grading Schemes” below).

Choose/Create New Grading Schemes

Click on the View Grading Scheme link under Display Grade as to choose the appropriate grading scheme.

Click on the Select Another Scheme link at the top right to select another grading scheme.

• To create a new grading scheme, click manage grading schemes link at the bottom right, then click the Add grading scheme button on the right.

Use Grading Scheme for the Total Grade in Your Course

You can display the Total grade of your course as a letter/performance grade by going to Settings > Course Details > Select the check box for Enable course grading scheme > Choose the appropriate grading scheme > Click the Update Course Details button at the bottom of the page.

To enable grading scheme for the course total grade, go to course Settings , check the Enable course grading scheme box, click the Select grading scheme link, then select the appropriate grading scheme, click Done , then click the maroon Update Course Details button.

VI. Curving Grades

You can use the Canvas Gradebook to curve grades for individual assignments. When you enter a desired average grade, Canvas will automatically adjust the scores as a bell curve 66% around the average curve.

Grade curving is available for assignments only ; if you wish to curve the total grade of a course, you will need to do so manually. Grade curving cannot be undone (although you can use Gradebook History to view pre-curved grades) and is advisable in courses where only a certain number of students can pass, or when you require a fixed distribution of grades distributed throughout the class.

Step-by-step instructions on curving grades are available at: https://community.canvaslms.com/docs/DOC-12832-415255003

VII. Giving Extra Credit

Do you want to give extra credit to students but are unsure how get Canvas Gradebook to recognize it? There are a few ways to do this:

Method 1: Add Extra Points to an Existing Assignment/Quiz

You can give extra credit to a particular assignment by adding the extra points to the total points a student scored, even if the student received a perfect score. Canvas allows you to give points greater than the highest possible points.

For example, If an assignment is worth a total of 100 points, a student earned a perfect score of 100, and you want to reward them with 5 extra credit points, you can enter 105 as the grade for the assignment.

If you use Canvas’ SpeedGrader for grading, you can enter the extra points in SpeedGrader. If you use rubrics in conjunction with SpeedGrader, you can add the extra points either to an existing rubric criterion or to an “Extra Credit” criterion. If you decide to add an “Extra Credit” criterion, make sure that the assignment point total excludes the total maximum extra credit points (i.e. the rubric is worth more points than the assignment) so that the actual assignment points are not affected by whether a student receives extra credit or not.

For example, if your rubric has four criteria with 4 maximum points each, and an “extra credit” criterion with 2 points each, then the maximum point total for your rubric is 4×4 + 2 = 18 points. But your assignment point total should be 16 points.

You can give extra credit in Quizzes as well. To adjust the point value for an entire quiz, use fudge points .

Method 2: Grant Extra Points in a Stand-alone “Extra Credit” Assignment and Gradebook Column

If you want to keep track of extra credit for the course as a whole, you can create a stand-alone extra credit assignment and gradebook column and adjust a student’s points as needed.

If you don’t weight your grades , you can create a separate assignment with 0 points. Any extra points given in this gradebook column will be added to the total points for the course.

If you weight your grades with assignment groups, you will need to create an extra credit assignment group with a weight greater than 0% and an assignment with greater than 0 points in order for Canvas Gradebook to calculate the total score correctly. All the assignment groups in your course plus the extra credit assignment group should weigh more than 100% in total.

One example of a correct setup for assignment groups with a maximum of 10% (or 10 points) extra credit for the course is:

Notice that the first 4 assignment groups, containing assignments that all students are assessed on, total to 100%. This ensures that any assignment placed within the Extra Credit assignment group will have either a positive or neutral effect on your students’ overall grade.

• If you are weighting your assignment groups, please pay attention to how weighted groups can affect the Gradebook if assignments are worth zero points.
• If you have drop rules set in an assignment group, adding extra points may affect your students’ scores.

For a detailed, step-by-step guide on how to give extra credit within Canvas, see: https://community.canvaslms.com/docs/DOC-9940-415278195

VIII. Tools and Course Setup for Multiple TAs

If you have multiple TAs working from the same Canvas course site and they are each assigned to a specific group of students, Academic Technology Solutions can help you set up your course site so that they only see the grades of the students they are responsible for. To get started, email the URL of your course site and a brief description of your needs to [email protected] .

IX. Excluding an Assignment from the Course’s Final Grades

If you wish to provide feedback for assignments without the assignment counting toward Gradebook calculations, you can exclude the assignment in the final grade calculation. (Note: this excludes the grade for all students. If you want to assign an assignment to a specific group of students, you should specifically assign course sections , assign individual students , or assign course groups to the assignment.)

For step-by-step instructions, see: https://community.canvaslms.com/docs/DOC-10120-4152618765

Alternatively, you can have Canvas automatically drop the lowest (or highest) grade in an assignment group. See https://community.canvaslms.com/docs/DOC-9880-4152232976 for step-by-step instructions.

X. Filtering by Modules, Automatic Late Policies, & Other New, Helpful Functions in the New Gradebook

In January 2018, Canvas released the New Gradebook, which offers a number of enhanced features, such as filtering by modules, automatic late policies, and customizable coloring. The current gradebook is expected to be deprecated and replaced by the New Gradebook sometime in the second half of 2018. For more information on how to opt-in and use the new features, see ATS’ “ Introducing the New Gradebook ” blog post.

Canvas assignment groups.

The Assignments page is arguably the most central to successful Canvas course utilization.

• It controls the columns in the gradebook and gradebook calculations.
• It displays all things gradable, including assignments, gradable discussions, and quizzes. Each can be created in Assignments.
• Dates used in the syllabus and calendar are rapidly edited in Assignments.

Use assignment groups to achieve:

• Assignment categorization
• Drop lowest  n  scores
• Drop highest  n  scores
• Never drop  x  assignment
• Weighting of grades

Canvas creates a group called "Assignments" by default, but you can change the group title or create additional groups. Because the default group is Assignments, Canvas places all assignment types into that group. When you are creating a new assignment, graded discussion, or quiz you will have the option to designate it as belonging to a previously created assignment group.

How Do I Use Assignment Groups in Canvas?

In Canvas, assignment groups allow you to organize your assignments into discrete groups. For example, you may want to group all the essay assignments in your course within one assignment group titled ‘Essays’.

Assignment groups allow you to leverage a weighted grade scheme in your Canvas course. A weighted grade scheme allows you to distribute percentages of a student’s final grade across these assignment groups. Following our previous example, you may want the Essays group to account for 30% of the final grade. 

By default, Grade weighting is turned off for all Canvas courses. To turn on Grade weighting, please follow Canvas’ tutorial for weighting final grades based on Assignment Groups.

How do grade weights get distributed across an Assignment Group?

In Canvas, the weight of an assignment group is distributed proportionally across the assignments inside it. Because of this, assignments worth different points will be weighted differently if they are in the same assignment group.

Here’s an example of an assignment group in Canvas. This group is worth 30% of the total grade and contains three assignments with different point values. The table further below outlines how the assignment group weight of 30% is distributed across the three Assignments.

Here, since Essay Two is out of 200 points, it will count two times more than Essays One and Three.

***assignment group weight distribution for assignments with differing point totals.

If you want all assignments within a given assignment group to be worth the same weight, you have two options:

1. Make all assignments inside an assignment group worth the same number of points, as shown below.

***In this scenario, we have changed Essay Two’s point value from 200 to 100 points. Since all point values in this assignment Group are the same, each Assignment will be worth the same, 10% in this case.

2. Create new assignment groups for any outlier assignments if you cannot or do not want to change their point value.

***In this scenario, we have not changed Essay Two’s point values, so we will need to put it in its own assignment group worth 10% and change the first assignment group to be worth 20% so that all Essays are now worth 10% of the total grade.

Designing Peer and Group Assignments for Online Courses

Audrey Wick is an English professor at Blinn College in central Texas

Writing skills are important for college students at any stage. Whether they are in a writing-intensive course or simply using their skills to navigate a traditional course, strength in written communication will help students be successful, lifelong learners.

For instructors, one step toward that success is designing peer and/or group assignments to help students develop these important skills. But when instructors themselves face uncertainty of student population and modality, how can they effectively plan for these types of assignments?

Redefine What Constitutes “Group” Assignments

In terms of traditional pedagogical thinking, “group” assignments generally mean three or more students working in collaboration toward a singular goal. But collaboration can occur in pairs as well. Often, working with one other individual can still help students practice important skills of planning, drafting and revision. When courses are small or retention becomes an issue, pairing students who are active and engaged in the class can help ensure that no one goes missing-in-action for the duration of an assignment.

Also, by keeping groups small, whether through pairs or not, assignments can often be accomplished in a much shorter amount of time. For instance, in the English environment, peer editing is streamlined through the use of pairing rather than trying to accomplish this in small groups. For those instructors who want more students to contribute to the assignment, pairing can happen more than once.

When peer editing , I frequently pair students—and then pair them again. That way, they get more than one perspective in feedback but are only focused on providing that in one-on-one settings. This keeps the assignment manageable for them to complete as well as for me, as the instructor, to track.

Avoid the Pitfall of Expecting a Face-to-Face Result When Online

When assignments are adapted to the online learning environment , instructors should not try to—necessarily—translate a face-to-face project into a digital application. That’s because organic parts of the process like brainstorming may not work synergistically online.

Nonetheless, if an instructor gives the group a starting point and direct guidance for the end goals (think: due date, submission format, required length, research requirements, etc.), this will take the guesswork out of the initial group work and help the students work more effectively.

Let Existing Technology Be Assistive

There is no need to reinvent writing process stages or try to build digital assignments from the ground up. Instead, tap into existing platforms at your institution or through your textbook publisher in order to create effective group assignments that work.

Many textbooks have digital components, companion websites, assistive project arms and more. For instance, writing instructors have several options for programs students can use for electronic portfolios, document sharing and peer editing. The technology here can connect students in digital pairs and groups, giving them the flexibility of space and time to complete the assignments collaboratively in a fully online environment.

Don’t Overlook Institutional Resources

Does your college have a library, learning lab, tutoring center or campus computer technicians that are student-facing? Likely your institution already has tools that you can use in creating and managing peer and group assignments.

For starters, speak with librarians at your institution, or research existing digital tools available through the library page. Many have how-to videos, style guides, plagiarism tutorials and more. Link these through your digital classroom or import them to your Learning Management System. Viola! Tailored content at their fingertips!

You’re Ready!

Incorporating collaboration opportunities is one way instructors can help students feel more connected in their college classes, no matter what their digital landscape looks like.

Introduction to assignments and assignment groups

Assignments are graded coursework. After creating assignments, your students can then interact with them in various ways (taking tests, uploading files, leaving comments, etc.), and you, in turn, can grade them. As you grade assignments, Populi automatically calculates your students' final course grades based on how you've weighted the assignments.

Assignment groups are broad categories of assignments. For example:

Assignments are particular items of graded course work. For example:

• Read chapters 1-8 of The Elements of Style
• Write a 1,000-word essay on Wendell Berry
• Dissect drosophilia melanogaster

The distinction between assignment groups and assignments gives you two options for how you grade your course.

• If you base your course grade on the weight you give to types of assignments—i.e., Readings = 25%, Papers = 50%, Lab Work = 25%—then use assignment groups.
• If you base your course grade on an average of all assignments without respect to their type, then skip assignment groups and just use assignments.

Read about grade weighting to learn more about how Populi calculates the course grade from the grades you give students on their assignments.

Assignment types

Each assignment type lets you and the student comment back and forth (and even attach files to the comments).

• Grade-only: Just give the student a grade. It's good for things like readings and other simple assignments that don't require a lot of interaction.
• File: Requires the student to submit a file to you for evaluation; good for essays, papers, etc. that benefit from feedback, revisions, and other interaction. The maximum file size is 5GB.
• Test: Creates a corresponding online test .
• Attendance: Calculates an assignment grade based on the student's attendance of course meeting times .
• Discussion: Creates a corresponding discussion .
• Essay: These provide students with a WYSIWYG editor that they can use to compose and format an essay-length composition right in Populi.
• Peer Review: Peer-review files and essays let other students in the course section view, comment on, and even grade the student's work. Read more about peer-review assignments .

You can attach any kind of assignment to a Lesson .

Teaching excellence & educational innovation, what are the benefits of group work.

“More hands make for lighter work.” “Two heads are better than one.” “The more the merrier.”

These adages speak to the potential groups have to be more productive, creative, and motivated than individuals on their own.

Benefits for students

Group projects can help students develop a host of skills that are increasingly important in the professional world (Caruso & Woolley, 2008; Mannix & Neale, 2005). Positive group experiences, moreover, have been shown to contribute to student learning, retention and overall college success (Astin, 1997; Tinto, 1998; National Survey of Student Engagement, 2006).

Properly structured, group projects can reinforce skills that are relevant to both group and individual work, including the ability to: 

• Break complex tasks into parts and steps
• Plan and manage time
• Refine understanding through discussion and explanation
• Give and receive feedback on performance
• Challenge assumptions
• Develop stronger communication skills.

Group projects can also help students develop skills specific to collaborative efforts, allowing students to...

• Tackle more complex problems than they could on their own.
• Delegate roles and responsibilities.
• Share diverse perspectives.
• Pool knowledge and skills.
• Hold one another (and be held) accountable.
• Receive social support and encouragement to take risks.
• Develop new approaches to resolving differences. 
• Establish a shared identity with other group members.
• Find effective peers to emulate.
• Develop their own voice and perspectives in relation to peers.

While the potential learning benefits of group work are significant, simply assigning group work is no guarantee that these goals will be achieved. In fact, group projects can – and often do – backfire badly when they are not designed , supervised , and assessed in a way that promotes meaningful teamwork and deep collaboration.

Benefits for instructors

Faculty can often assign more complex, authentic problems to groups of students than they could to individuals. Group work also introduces more unpredictability in teaching, since groups may approach tasks and solve problems in novel, interesting ways. This can be refreshing for instructors. Additionally, group assignments can be useful when there are a limited number of viable project topics to distribute among students. And they can reduce the number of final products instructors have to grade.

Whatever the benefits in terms of teaching, instructors should take care only to assign as group work tasks that truly fulfill the learning objectives of the course and lend themselves to collaboration. Instructors should also be aware that group projects can add work for faculty at different points in the semester and introduce its own grading complexities .

A group project is a cooperative learning assignment that requires students to work with peer group members to plan, discuss, and complete a specific project, often over the course of an entire semester. The project can be a research paper, an in-class oral presentation, an out-of-class study project, or research contributed as part of a larger class project involving multiple student groups . The purpose is to prepare students to work collaboratively in order to develop the intellectual and social skills needed to examine research problems from a variety of perspectives, to communicate effectively with their peers, and to evaluate and resolve issues on their own with support from other group members.

Benefits of Group Work

As stressful as it can be, group work can actually be beneficial in the long run because it closely parallels the dynamics of serving on a committee, participating in a task force, or working on a collaborative project found in most professional workplace settings. Whatever form the group assignment takes in your course, the opportunity to work with others, rather than on your own, can provide distinct benefits. These include:

• Increased productivity and performance -- groups that work well together can achieve much more than individuals working on their own. A broader range of skills can be applied to practical activities and the process of sharing and discussing ideas can play a pivotal role in deepening your understanding of the research problem. This process also enhances opportunities for applying strategies of critical inquiry and creative or radical problem-solving to an issue.
• Skills development -- being part of a team will help you develop your interpersonal skills. This can include expressing your ideas clearly, listening carefully to others, participating effectively in group deliberations, and clearly articulating to group members t he results of your research . Group work can also help develop collaborative skills, such as, team-based leadership and effectively motivating others. These skills will be useful throughout your academic career and all are highly sought after by employers.
• Knowing more about yourself -- working with others will help identify your own strengths and weaknesses in a collaborative context. For example, you may be a better leader than listener, or, you might be good at coming up with the 'big idea' but not so good at developing a specific plan of action. Enhanced self-awareness about the challenges you may have in working with others will enhance overall learning experiences. Here again, this sense about yourself will be invaluable when you enter the workforce.

Stages of Group Work

I.  Getting Started

To ensure that your group gets off to a good start, it may be beneficial to:

• Take time for all members to introduce themselves, including name, background, and stating specific strengths in contributing to the overall goals of the assignment.
• Nominate or vote to have someone act as the group leader or facilitator or scheduler. If the burden might be too great, consider deciding to rotate this responsibility among all group members.
• Exchange current contact information, such as, email addresses, social media information, and cell phone numbers.
• Consider creating an online workspace account to facilitate discussions, editing documents, sharing files, exchanging ideas, and to manage a group calendar. There are many free online platforms available for this type of work such as Google docs.

II.  Discussing Goals and Tasks

After you and the other members of the group agree about how to approach the assignment, take time to make sure everyone understands what it is they will need to achieve. Consider the following:

• What are the goals of the assignment? Develop a shared understanding of the assignment's expected learning outcomes to ensure that everyone knows what their role is supposed to be within the group.
• Note when the assignment is due [or when each part is due] so that everyone is on the same schedule and any potential conflicts with assignment due dates in other classes can be addressed ahead of time by each members of the group.
• Discuss how you are going to specifically meet the requirements of the assignment. For example, if the assignment is to write a sample research grant, what topic are you going to research and what organizations would you solicit funding from?
• If your professor allows considerable flexibility in pursuing the goals of the assignment, it often helps to brainstorm a number of ideas and then assess the merits of each one separately. As a group, reflect upon the following questions: How much do you know about this topic already? Is the topic interesting to everyone? If it is not interesting to some, they may not be motivated to work as hard as they might on a topic they found interesting. Can you do a good job on this topic in the available time? With the available people? With the available resources? How easy or hard would it be to obtain good information on the topic? [ NOTE:   Consult with a librarian before assuming that information may be too difficult to find!].

III.  Planning and Preparation

This is the stage when your group should plan exactly what needs to be done, how it needs to be done, and determine who should do what. Pay attention to the following:

• Work together to break the project up into separate tasks and decide on the tasks or sub-tasks each member is responsible for. Make sure that work is equally distributed among each member of the group.
• Agree on the due-dates for completing each task, keeping in mind that members will need time to review any draft documents and the group must have time at the end to pull everything together.
• Develop mechanisms for keeping in touch, meeting periodically, and the preferred methods for sharing information. Discuss and identify any potential stumbling blocks that may arise that could hinder your work [e.g., mid-terms].

NOTE:   Try to achieve steps 1, 2, and 3 in a group meeting that is scheduled as soon as possible after you have received the assignment and your group has been formed. The sooner these preliminary tasks are agreed upon, the sooner each group member can focus on their particular responsibilities.

IV.  Implementation

While each member carries out their individual tasks, it is important to preserve your group's focus and sense of purpose. Effective communication is vital, particularly when your group activity extends over an extended period of time. Here are some tips to promote good communication:

• Keep in touch with each other frequently, reporting progress regularly. When the group meets for the first time, think about about setting up a regular day and time for people to report on their progress [either in-person or online].
• If someone is having trouble completing his or her area of responsibility, work with that person to figure out how to solve the problem. Be supportive and helpful, but don't offer to do other people's work.
• At the same time, make it clear that the group is depending on everyone to do their part; all group members should agree that it is detrimental to everyone in the group for one person to show up at the last minute without his or her work done.

V.  Finishing Up

Be sure to leave enough time to put all the pieces together before the group project is due and to make sure nothing has been forgotten [e.g., someone forgot to correct a chart or a page is missing]. Synthesizing each group member's work usually requires some negotiation and, collectively, overcoming any existing obstacles towards completion. Technically, this can be done online, but it is better to meet in person to ensure that everyone is actively involved in the process.

If your group has to give a presentation about the results of their research, go through the same process--decide who is going to do what and give everyone enough time to prepare and practice ahead of time [preferably together]. At this point before the assignment is due, it is vital to ensure that you pay particular attention to detail, tie up any loose ends, and review the research project together as a team rather than just looking over individual contributions.

VI.  Writing Up Your Project

Writing the group report can be challenging; it is critical that you leave enough time for this final stage. If your group decided to divide responsibility for drafting sections, you will need to nominate a member of the group [if not done so already] to bring everything together so that the narrative flows well and isn't disjointed. Make it their assignment rather than assigning that person to also write a section of the report. It is best to choose whomever in your group is the best writer because careful copy editing at this stage is essential to ensure that the final document is well organized and logically structured.

Focus on the following:

• Have all the writers in your group use the same writing style [e.g., verb tense, diction or word choice, tone, voice, etc.]?
• Are there smooth transitions between individual sections?
• Are the citations to sources, abbreviations, and non-textual elements [charts, graphs, tables, etc.] consistent?

Meeting Tip

Where Your Group Meets Matters!

Choosing where to you meet can have as much of an impact on your group's overall success as how well you communicate and work together. When your group is first formed, be sure to set aside some time to discuss and come to an agreement about where to meet in the future. Obviously, convenience has a lot to do with your possible choices. However, discussions of where to meet should also focus on identifying a space that's comfortable, easily accessible to everyone, and does not have any distractions, such as, the smell of food from nearby, heavy foot traffic, or constant noise.

Places that meet all of these conditions are the collaborative workrooms in the East Asian Library of Doheny or the group study spaces in the Lower Computer Commons of Leavey Library or on the second floor of Leavey Library. These rooms can seat anywhere from 4 to 10 people and all have dry erase boards and power and network connectivity. Most rooms also have large monitors with laptop connections that your group can use to display a presentation, document, spreadsheet, or other information that is the focus of your collaborative work. Note that these rooms are very popular, especially towards the end of the semester, so schedule early and be courteous in promptly cancelling your reservation if needed so others can use the room.

Bilandzic, Mark and Marcus Foth. "Libraries as Coworking Spaces: Understanding User Motivations and Perceived Barriers to Social Learning," Library Hi Tech 31 (2013): 254-273.

Another Meeting Tip

Meeting Virtually

Group project meetings do not have to meet in-person. Meeting online has the advantages of being able to schedule meetings at any time rather than working around when a venue is available, being able to easily view documents through screen share or to work collaboratively on a document, and being able to record the meeting so that members can go back and review what was discussed.

However, it is important to be aware that online group meetings present their own unique challenges. This can include technology problems. For example, if a group member is having connectivity issues during a meeting, they become disconnected from the proceedings and can’t participate. Even if the issue is resolved, time then has to be taken to catch them up on any discussions they may have missed. Depending on where a group member is logging into the meeting, it may be more likely there will be unexpected disruptions, whereas, the group has total control over the location of in-person meetings in order to eliminate the possibility of distractions. Remote meeting platforms do not facilitate important side conversations that can easily take place in-person. Side conversations, such as, two members quickly discussing when to meet to work on a part of the project together, is difficult to do online. If it takes place over chat, it takes longer to have a conversation and your focus is on typing into chat rather than hearing what else is taking place. Finally, if your group decides to meet remotely, ensure that all group members have an equal opportunity to contribute and be heard.

Random Assignment in Psychology (Definition + 40 Examples)

Have you ever wondered how researchers discover new ways to help people learn, make decisions, or overcome challenges? A hidden hero in this adventure of discovery is a method called random assignment, a cornerstone in psychological research that helps scientists uncover the truths about the human mind and behavior.

Random Assignment is a process used in research where each participant has an equal chance of being placed in any group within the study. This technique is essential in experiments as it helps to eliminate biases, ensuring that the different groups being compared are similar in all important aspects.

By doing so, researchers can be confident that any differences observed are likely due to the variable being tested, rather than other factors.

In this article, we’ll explore the intriguing world of random assignment, diving into its history, principles, real-world examples, and the impact it has had on the field of psychology.

History of Random Assignment

Stepping back in time, we delve into the origins of random assignment, which finds its roots in the early 20th century.

The pioneering mind behind this innovative technique was Sir Ronald A. Fisher , a British statistician and biologist. Fisher introduced the concept of random assignment in the 1920s, aiming to improve the quality and reliability of experimental research .

His contributions laid the groundwork for the method's evolution and its widespread adoption in various fields, particularly in psychology.

Fisher’s groundbreaking work on random assignment was motivated by his desire to control for confounding variables – those pesky factors that could muddy the waters of research findings.

By assigning participants to different groups purely by chance, he realized that the influence of these confounding variables could be minimized, paving the way for more accurate and trustworthy results.

Early Studies Utilizing Random Assignment

Following Fisher's initial development, random assignment started to gain traction in the research community. Early studies adopting this methodology focused on a variety of topics, from agriculture (which was Fisher’s primary field of interest) to medicine and psychology.

The approach allowed researchers to draw stronger conclusions from their experiments, bolstering the development of new theories and practices.

One notable early study utilizing random assignment was conducted in the field of educational psychology. Researchers were keen to understand the impact of different teaching methods on student outcomes.

By randomly assigning students to various instructional approaches, they were able to isolate the effects of the teaching methods, leading to valuable insights and recommendations for educators.

Evolution of the Methodology

As the decades rolled on, random assignment continued to evolve and adapt to the changing landscape of research.

Advances in technology introduced new tools and techniques for implementing randomization, such as computerized random number generators, which offered greater precision and ease of use.

The application of random assignment expanded beyond the confines of the laboratory, finding its way into field studies and large-scale surveys.

Researchers across diverse disciplines embraced the methodology, recognizing its potential to enhance the validity of their findings and contribute to the advancement of knowledge.

From its humble beginnings in the early 20th century to its widespread use today, random assignment has proven to be a cornerstone of scientific inquiry.

Its development and evolution have played a pivotal role in shaping the landscape of psychological research, driving discoveries that have improved lives and deepened our understanding of the human experience.

Delving into the heart of random assignment, we uncover the theories and principles that form its foundation.

The method is steeped in the basics of probability theory and statistical inference, ensuring that each participant has an equal chance of being placed in any group, thus fostering fair and unbiased results.

Basic Principles of Random Assignment

Understanding the core principles of random assignment is key to grasping its significance in research. There are three principles: equal probability of selection, reduction of bias, and ensuring representativeness.

The first principle, equal probability of selection , ensures that every participant has an identical chance of being assigned to any group in the study. This randomness is crucial as it mitigates the risk of bias and establishes a level playing field.

The second principle focuses on the reduction of bias . Random assignment acts as a safeguard, ensuring that the groups being compared are alike in all essential aspects before the experiment begins.

This similarity between groups allows researchers to attribute any differences observed in the outcomes directly to the independent variable being studied.

Lastly, ensuring representativeness is a vital principle. When participants are assigned randomly, the resulting groups are more likely to be representative of the larger population.

This characteristic is crucial for the generalizability of the study’s findings, allowing researchers to apply their insights broadly.

Theoretical Foundation

The theoretical foundation of random assignment lies in probability theory and statistical inference .

Probability theory deals with the likelihood of different outcomes, providing a mathematical framework for analyzing random phenomena. In the context of random assignment, it helps in ensuring that each participant has an equal chance of being placed in any group.

Statistical inference, on the other hand, allows researchers to draw conclusions about a population based on a sample of data drawn from that population. It is the mechanism through which the results of a study can be generalized to a broader context.

Random assignment enhances the reliability of statistical inferences by reducing biases and ensuring that the sample is representative.

Differentiating Random Assignment from Random Selection

It’s essential to distinguish between random assignment and random selection, as the two terms, while related, have distinct meanings in the realm of research.

Random assignment refers to how participants are placed into different groups in an experiment, aiming to control for confounding variables and help determine causes.

In contrast, random selection pertains to how individuals are chosen to participate in a study. This method is used to ensure that the sample of participants is representative of the larger population, which is vital for the external validity of the research.

While both methods are rooted in randomness and probability, they serve different purposes in the research process.

Understanding the theories, principles, and distinctions of random assignment illuminates its pivotal role in psychological research.

This method, anchored in probability theory and statistical inference, serves as a beacon of reliability, guiding researchers in their quest for knowledge and ensuring that their findings stand the test of validity and applicability.

Methodology of Random Assignment

Implementing random assignment in a study is a meticulous process that involves several crucial steps.

The initial step is participant selection, where individuals are chosen to partake in the study. This stage is critical to ensure that the pool of participants is diverse and representative of the population the study aims to generalize to.

Once the pool of participants has been established, the actual assignment process begins. In this step, each participant is allocated randomly to one of the groups in the study.

Researchers use various tools, such as random number generators or computerized methods, to ensure that this assignment is genuinely random and free from biases.

Monitoring and adjusting form the final step in the implementation of random assignment. Researchers need to continuously observe the groups to ensure that they remain comparable in all essential aspects throughout the study.

If any significant discrepancies arise, adjustments might be necessary to maintain the study’s integrity and validity.

Tools and Techniques Used

The evolution of technology has introduced a variety of tools and techniques to facilitate random assignment.

Random number generators, both manual and computerized, are commonly used to assign participants to different groups. These generators ensure that each individual has an equal chance of being placed in any group, upholding the principle of equal probability of selection.

In addition to random number generators, researchers often use specialized computer software designed for statistical analysis and experimental design.

These software programs offer advanced features that allow for precise and efficient random assignment, minimizing the risk of human error and enhancing the study’s reliability.

Ethical Considerations

The implementation of random assignment is not devoid of ethical considerations. Informed consent is a fundamental ethical principle that researchers must uphold.

Informed consent means that every participant should be fully informed about the nature of the study, the procedures involved, and any potential risks or benefits, ensuring that they voluntarily agree to participate.

Beyond informed consent, researchers must conduct a thorough risk and benefit analysis. The potential benefits of the study should outweigh any risks or harms to the participants.

Safeguarding the well-being of participants is paramount, and any study employing random assignment must adhere to established ethical guidelines and standards.

Conclusion of Methodology

The methodology of random assignment, while seemingly straightforward, is a multifaceted process that demands precision, fairness, and ethical integrity. From participant selection to assignment and monitoring, each step is crucial to ensure the validity of the study’s findings.

The tools and techniques employed, coupled with a steadfast commitment to ethical principles, underscore the significance of random assignment as a cornerstone of robust psychological research.

Benefits of Random Assignment in Psychological Research

The impact and importance of random assignment in psychological research cannot be overstated. It is fundamental for ensuring the study is accurate, allowing the researchers to determine if their study actually caused the results they saw, and making sure the findings can be applied to the real world.

Facilitating Causal Inferences

When participants are randomly assigned to different groups, researchers can be more confident that the observed effects are due to the independent variable being changed, and not other factors.

This ability to determine the cause is called causal inference .

This confidence allows for the drawing of causal relationships, which are foundational for theory development and application in psychology.

Ensuring Internal Validity

One of the foremost impacts of random assignment is its ability to enhance the internal validity of an experiment.

Internal validity refers to the extent to which a researcher can assert that changes in the dependent variable are solely due to manipulations of the independent variable , and not due to confounding variables.

By ensuring that each participant has an equal chance of being in any condition of the experiment, random assignment helps control for participant characteristics that could otherwise complicate the results.

Enhancing Generalizability

Beyond internal validity, random assignment also plays a crucial role in enhancing the generalizability of research findings.

When done correctly, it ensures that the sample groups are representative of the larger population, so can allow researchers to apply their findings more broadly.

This representative nature is essential for the practical application of research, impacting policy, interventions, and psychological therapies.

Limitations of Random Assignment

Potential for implementation issues.

While the principles of random assignment are robust, the method can face implementation issues.

One of the most common problems is logistical constraints. Some studies, due to their nature or the specific population being studied, find it challenging to implement random assignment effectively.

For instance, in educational settings, logistical issues such as class schedules and school policies might stop the random allocation of students to different teaching methods .

Ethical Dilemmas

Random assignment, while methodologically sound, can also present ethical dilemmas.

In some cases, withholding a potentially beneficial treatment from one of the groups of participants can raise serious ethical questions, especially in medical or clinical research where participants' well-being might be directly affected.

Researchers must navigate these ethical waters carefully, balancing the pursuit of knowledge with the well-being of participants.

Generalizability Concerns

Even when implemented correctly, random assignment does not always guarantee generalizable results.

The types of people in the participant pool, the specific context of the study, and the nature of the variables being studied can all influence the extent to which the findings can be applied to the broader population.

Researchers must be cautious in making broad generalizations from studies, even those employing strict random assignment.

Practical and Real-World Limitations

In the real world, many variables cannot be manipulated for ethical or practical reasons, limiting the applicability of random assignment.

For instance, researchers cannot randomly assign individuals to different levels of intelligence, socioeconomic status, or cultural backgrounds.

This limitation necessitates the use of other research designs, such as correlational or observational studies , when exploring relationships involving such variables.

Response to Critiques

In response to these critiques, people in favor of random assignment argue that the method, despite its limitations, remains one of the most reliable ways to establish cause and effect in experimental research.

They acknowledge the challenges and ethical considerations but emphasize the rigorous frameworks in place to address them.

The ongoing discussion around the limitations and critiques of random assignment contributes to the evolution of the method, making sure it is continuously relevant and applicable in psychological research.

While random assignment is a powerful tool in experimental research, it is not without its critiques and limitations. Implementation issues, ethical dilemmas, generalizability concerns, and real-world limitations can pose significant challenges.

However, the continued discourse and refinement around these issues underline the method's enduring significance in the pursuit of knowledge in psychology.

By being careful with how we do things and doing what's right, random assignment stays a really important part of studying how people act and think.

Random Assignment in Experiments | Introduction & Examples

Published on March 8, 2021 by Pritha Bhandari . Revised on June 22, 2023.

In experimental research, random assignment is a way of placing participants from your sample into different treatment groups using randomization.

With simple random assignment, every member of the sample has a known or equal chance of being placed in a control group or an experimental group. Studies that use simple random assignment are also called completely randomized designs .

Random assignment is a key part of experimental design . It helps you ensure that all groups are comparable at the start of a study: any differences between them are due to random factors, not research biases like sampling bias or selection bias .

Table of contents

Why does random assignment matter, random sampling vs random assignment, how do you use random assignment, when is random assignment not used, other interesting articles, frequently asked questions about random assignment.

Random assignment is an important part of control in experimental research, because it helps strengthen the internal validity of an experiment and avoid biases.

In experiments, researchers manipulate an independent variable to assess its effect on a dependent variable, while controlling for other variables. To do so, they often use different levels of an independent variable for different groups of participants.

This is called a between-groups or independent measures design.

You use three groups of participants that are each given a different level of the independent variable:

• a control group that’s given a placebo (no dosage, to control for a placebo effect ),
• an experimental group that’s given a low dosage,
• a second experimental group that’s given a high dosage.

Random assignment to helps you make sure that the treatment groups don’t differ in systematic ways at the start of the experiment, as this can seriously affect (and even invalidate) your work.

If you don’t use random assignment, you may not be able to rule out alternative explanations for your results.

• participants recruited from cafes are placed in the control group ,
• participants recruited from local community centers are placed in the low dosage experimental group,
• participants recruited from gyms are placed in the high dosage group.

With this type of assignment, it’s hard to tell whether the participant characteristics are the same across all groups at the start of the study. Gym-users may tend to engage in more healthy behaviors than people who frequent cafes or community centers, and this would introduce a healthy user bias in your study.

Although random assignment helps even out baseline differences between groups, it doesn’t always make them completely equivalent. There may still be extraneous variables that differ between groups, and there will always be some group differences that arise from chance.

Most of the time, the random variation between groups is low, and, therefore, it’s acceptable for further analysis. This is especially true when you have a large sample. In general, you should always use random assignment in experiments when it is ethically possible and makes sense for your study topic.

Random sampling and random assignment are both important concepts in research, but it’s important to understand the difference between them.

Random sampling (also called probability sampling or random selection) is a way of selecting members of a population to be included in your study. In contrast, random assignment is a way of sorting the sample participants into control and experimental groups.

While random sampling is used in many types of studies, random assignment is only used in between-subjects experimental designs.

Some studies use both random sampling and random assignment, while others use only one or the other.

Random sampling enhances the external validity or generalizability of your results, because it helps ensure that your sample is unbiased and representative of the whole population. This allows you to make stronger statistical inferences .

You use a simple random sample to collect data. Because you have access to the whole population (all employees), you can assign all 8000 employees a number and use a random number generator to select 300 employees. These 300 employees are your full sample.

Random assignment enhances the internal validity of the study, because it ensures that there are no systematic differences between the participants in each group. This helps you conclude that the outcomes can be attributed to the independent variable .

• a control group that receives no intervention.
• an experimental group that has a remote team-building intervention every week for a month.

You use random assignment to place participants into the control or experimental group. To do so, you take your list of participants and assign each participant a number. Again, you use a random number generator to place each participant in one of the two groups.

To use simple random assignment, you start by giving every member of the sample a unique number. Then, you can use computer programs or manual methods to randomly assign each participant to a group.

• Random number generator: Use a computer program to generate random numbers from the list for each group.
• Lottery method: Place all numbers individually in a hat or a bucket, and draw numbers at random for each group.
• Flip a coin: When you only have two groups, for each number on the list, flip a coin to decide if they’ll be in the control or the experimental group.
• Use a dice: When you have three groups, for each number on the list, roll a dice to decide which of the groups they will be in. For example, assume that rolling 1 or 2 lands them in a control group; 3 or 4 in an experimental group; and 5 or 6 in a second control or experimental group.

This type of random assignment is the most powerful method of placing participants in conditions, because each individual has an equal chance of being placed in any one of your treatment groups.

Random assignment in block designs

In more complicated experimental designs, random assignment is only used after participants are grouped into blocks based on some characteristic (e.g., test score or demographic variable). These groupings mean that you need a larger sample to achieve high statistical power .

For example, a randomized block design involves placing participants into blocks based on a shared characteristic (e.g., college students versus graduates), and then using random assignment within each block to assign participants to every treatment condition. This helps you assess whether the characteristic affects the outcomes of your treatment.

In an experimental matched design , you use blocking and then match up individual participants from each block based on specific characteristics. Within each matched pair or group, you randomly assign each participant to one of the conditions in the experiment and compare their outcomes.

Sometimes, it’s not relevant or ethical to use simple random assignment, so groups are assigned in a different way.

When comparing different groups

Sometimes, differences between participants are the main focus of a study, for example, when comparing men and women or people with and without health conditions. Participants are not randomly assigned to different groups, but instead assigned based on their characteristics.

In this type of study, the characteristic of interest (e.g., gender) is an independent variable, and the groups differ based on the different levels (e.g., men, women, etc.). All participants are tested the same way, and then their group-level outcomes are compared.

When it’s not ethically permissible

When studying unhealthy or dangerous behaviors, it’s not possible to use random assignment. For example, if you’re studying heavy drinkers and social drinkers, it’s unethical to randomly assign participants to one of the two groups and ask them to drink large amounts of alcohol for your experiment.

When you can’t assign participants to groups, you can also conduct a quasi-experimental study . In a quasi-experiment, you study the outcomes of pre-existing groups who receive treatments that you may not have any control over (e.g., heavy drinkers and social drinkers). These groups aren’t randomly assigned, but may be considered comparable when some other variables (e.g., age or socioeconomic status) are controlled for.

Random sampling enhances the external validity or generalizability of your results, while random assignment improves the internal validity of your study.

Random assignment is used in experiments with a between-groups or independent measures design. In this research design, there’s usually a control group and one or more experimental groups. Random assignment helps ensure that the groups are comparable.

In general, you should always use random assignment in this type of experimental design when it is ethically possible and makes sense for your study topic.
