Exam I Grades Posted

The points for Exam I are posted on Blackboard. There were a few questions that a relatively large percentage of the class missed, so I calculated the points as the number of correct answers divided by 46.5.

With the curve, the statistics for the exam are:

Mean 79
StDev 12.74
Min 47
Max 105
Mode 82

The grade distribution is provided below. There were an equal number of A's and D's and F's, making it a pretty good normal distribution, although skewed slightly toward the higher end. This is about what you would expect from an exam.
