Research questions:

a) How to determine which section grades so deviate from the mean as to raise questions
 

Standard deviations?

Other tools?

b) If we add a column containing the overall GPA of each section, will this provide a measure that helps to explain the particular grades within a section?   (At Temple in general there is a .67 correlation between a student's overall GPA and his or her grade in an IH class.)

c)  Other?
