1.Cohort Correlation and Performance Analysis
Scatter plot and bar chart · 2026
An academic performance analyst bypassed manual workflows by automatically visualizing student cohort correlations from raw CSV data. A summary panel highlights that the highest average final grade (11.4) occurs in the 5-10 hrs/week study band, while the largest cohort (198 students) studies 2-5 hrs/week. A scatter plot visualizes absences versus final grade, colored by study time, with a red dashed line marking a pass threshold at a grade of 10. Bubble sizes represent second-period grades, allowing the analyst to spot patterns without calculating Pearson correlations manually. A bar chart displays the frequency of scores, peaking at a grade of 10 (56 students) and 11 (47 students).
