Description

Data on course evaluations, course characteristics, and professor characteristics for 463 courses for the academic years 2000–2002 at the University of Texas at Austin.

gender: factor indicating instructor's gender.
credits: factor. Is the course a single-credit elective (e.g., yoga, aerobics, dance)?
beauty: rating of the instructor's physical appearance by a panel of six students, averaged across the six panelists, shifted to have a mean of zero.
eval: course overall teaching evaluation score, on a scale of 1 (very unsatisfactory) to 5 (excellent).
division: factor. Is the course an upper or lower division course? (Lower division courses are mainly large freshman and sophomore courses)?
native: factor. Is the instructor a native English speaker?
tenure: factor. Is the instructor on tenure track?
