Selectivity | Total Fall 2020 COVID-19 Cases | Number of Institutions |
Highly selective | 18464 | 74 |
Less/non-selective | 27994 | 376 |
Most selective | 16612 | 74 |
Very selective | 24514 | 193 |
The top boxplot graphic shows the total number of undergraduates infected in the fall semester of 2020 by school selectivity. The vertical line in the green boxes indicates the median number of undergraduates infected in each category. Most selective schools have the highest median number of students infected, while less/non-selective schools have the lowest median number of students infected.
The bottom table shows the total number of COVID-19 cases among each category in the fall semester of 2020. In comparing the two graphs, it is interesting to note that while most selective schools have the highest median number of undergraduates infected, most selective schools have the lowest total number of infected graduates after summing the cases from each institution in this category. Similarly, while less/non-selective schools have the lowest median number of students infected, less/non-selective schools have the highest number of total cases. This phenomenon can be used to illustrate that outliers can greatly affect the total value, and that median value is not necessarily indicative of a bigger picture. It is also important to note that this visualization did not use the total number of undergraduates on campus within each category, and thus the number of undergraduates infected within each category is showcasing something different from the percentage of infected students on campus.
