Midterm exam histograms

Submitted by Adam R. Johnson, Harvey Mudd College
We all know that we are "supposed" to get Gaussian curves when we have a random sample of students taking our classes, but I certainly have never seen that.  Many of us are currently grading that first midterm now.  What shape best describes your histogram?  Add other options in the comments!


Maybe someone ought to alert a statistician...

Really, it is a bimodal distribution with a dearth of grades in the 'B' range.
