Currently, Score Details allow students to compare themselves to the class using a display of the minimum, mean, and maximum scores. The analytics displays use a box-and-whisker style. As an instructor, I find the latter is a far better choice.
Especially for larger classes (>40 or 50). There will always be outlier students. It is inappropriate for students to be comparing themselves to those outliers. For example, it is very common to have a non-participating student, resulting in a meaningless minimum score of zero.
There is also a subtle difference between showing the mean or median. The median is best for students to judge their performance against peers.
Box-and-whisker plots give a very intuitive display, easy to interpret even for students who aren't familiar with exactly how they are computed.
