Is there any systematic tendency for part-time college faculty to hold their students to different standards than do full-time faculty? An article reported that for a sample of 125 courses taught by full-time faculty, the mean course GPA was 2.7186 and the standard deviation was 0.67342, whereas for a sample of 88 courses taught by part-timers, the mean and standard deviation were 2.8639 and 0.53241, respectively.
