Show Score Details with Quartiles

[mclean]

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.

I've seen students like to see how they did to the class average and low/high scores. It's great that its viewed as a box plot but whenever some students get a 0 on a score (from not doing it), it will drastically shift the average and no longer show the true lowest score. There should be a function that shows a box plot that doesn't include non-submissions, so students can see a more accurate representation of the classes average.
