That is a pretty rough calculation. MIT has a lot of students who aren’t STEM, so are less likely to do research, which would affect the calculation. It doesn’t take research funding into account, either. Using this approach, Harvey Mudd has 94 FT faculty and 800 students. With no grad students to take research slots, seems like by your way of measuring Mudd would come out ahead. Mostly I am saying that your method is lousy, though. I’d like @firstsax to state his source.
