@David: It would be interesting to see this in the context of other numbered classes. How does the number of 300-level classes compare to the number of 400-level classes? Does Williams even have a consistent convention for what’s 300-level and what’s 400-level? I don’t really remember much of a distinction between 300’s and 400’s in terms of difficulty or depth.

What’s your x-axis?

“Number of 300-level courses” — Is the “number,” the class size, number of students registered is a 300-level course?
