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 2.7286 and the standard deviation was 0.68342, whereas for a sample of 88 courses taught by part-timers, the mean and standard deviation were 2.8539 and 0.53241, respectively. Does it appear that true average course GPA for part-time faculty differs from that...
