Canvas Analytics and the median value

So, here are the analytics for a particular midterm on our Canvas site:

So far, so good, right?


Well, when I look at the quiz statistics in the gradebook, I get this:


Average Score:49
High Score:58
Low Score:34
Total Graded Submissions:44 submissions


44 submissions, check. Sort by grade in the gradebook, count down 22 values and I find that I am in the exact middle of a group of five identical scores, all at 51 points.


How on earth does Canvas calculate a median score and get 50.4? Even if you add in three non-submissions as "values", you would still get a whole number (because our # of submissions is now odd). Anyone else getting these anomalous results?
