One of the first steps of any data analysis project is exploratory data analysis.. This involves exploring a dataset in three ways: 1. Summarizing a dataset using descriptive statistics.. 2. Visualizing a dataset using charts.. 3. Identifying missing values.. By performing these three actions, you can gain an understanding of how the values in a dataset are distributed and detect any ...

Figure 2 shows the study area, the location of the surface water bodies, and the location of the sampling points in the Culiacan River basin. Sampling site 1 (SP1) is located downstream of the Sanalona reservoir, SP9 is located downstream of the ALM reservoir, and SP6 is located where the two mainstreams join and form a single stream, the Culiacan River.

Bt technology has played significant role in controlling bollworms and increasing cotton yield in earlier days of its introduction, a subsequent decline in yield became apparent over time. This decline may be attributed to various environmental factors, pest dynamics, or combination of both. Therefore, the present biophysical survey and questionnaire were designed to evaluate the impact of Bt ...
