Interesting. 1,250 students surveyed and of those 437 were male, 813 female (if I have done my simultaneous equation correctly). Why the discrepancy? - Are white males currently less represented than white females on the surveyed campuses in the USA?

There is probably room here for the stats to vary widely by campus surveyed, potentially even across courses within a single college.

According to Kahneman (Thinking Fast and Slow), sample deficiencies are one of the biggest causes of incorrect deductions. Are there other surveys for comparison?

Colleges are roughly 40/60 M/F so this sample isn't too far out of whack. Further reducing to white only could easily make up the 5 point difference.
