The data set contains first-year grade point averages (GPAs) from 2397 Iowa university first-years who entered the university of Iowa as freshmen in the fall of 1978. The GPAs are separated out by two ordinal variables with 9 categories each, High-School-Ranking percentiles and ACT Classification.
A data frame with four columns:
ACT classification (ACT is an organization that offers, among other things, college entrance exams in the US; up to 1996, ACT stood for “American College Testing”.)
grade point average for the HSR/ACTC combination
sample size for the HSR/ACTC combination
