More on student evaluations of professors

“…the correlation between Quality and Easiness is 0.61, and the correlation between Quality and Sexiness is 0.30. Using simple linear regression, we find that about half of the variation in Quality is a function of Easiness and Sexiness.” The result is from three professors at Central Michigan University, reported by the SCSU Scholars blog. An earlier post of mine cited a paper by Michael Huemer, arguing that students reward easy professors with good evaluations.
