PSA: I realized a way to interpret the new "box plots" for a better Gestalt
Since all of the markers (10th, 25th, median, 75th, 90th) are all firm, by looking at these distributions, you can immediately get a sense where scores are concentrated. Let's take this example:
View attachment 218227
Let's compare the 25th-50th and 50th-75th. Both of these regions, by definition, have the same number of students. The 515-518 being smaller indicates there is a greater concentration of students there. By contrast, there same number of students are distributed over the 518-522 range.
Compare that plot to this one:
View attachment 218228
As you can see, a ton of students are concentrated in the 515-517 range. The same number are distributed over the broader 517-520 box. Fewer are distributed very broadly over the 510-515 range.
Tl;dr: Thin sections of the box plots indicate where many students are concentrated. Long stretches indicates there are students distributed broadly and are not the best regions to be in.
