Finding Independence

Experiment: A study has been performed to determine how students interact with professors. (Ok, it is currently being proformed here at Penn and so we don't have any data yet.) Students are observed raising their hands and data is recorded as to who gets called on. 1520's events are collected. The question of interest is whether male professors call on male students more or less than female students and likewise for female professors.

For each event, the following is recorded:

19 classes of data were collected with 80 observations taken in each class. 10 male professors and 10 female professors. (But one female professor used cold calling and so was eliminated from the study.) How should this be analyzed?

Different attacks

Naive logistic regression

Doesn't clustering hurt us statistically alot?
