From: STEM courses are harder: evaluating inter-course grading disparities with a calibrated GPA model
Average observed and calibrated GPA for STEM students (those who are in programs that result in B.S., B.Eng, and mathematics degrees) and non-STEM (all other programs). The observed GPA is 3.19 for non-STEM and 3.21 for STEM. The calibrated GPA is 2.90 for non-STEM and 3.32 for STEM. This implies that the observed non-STEM GPA is inflated by 0.29 points, and the observed STEM GPA is depressed by 0.12 points. The standard deviation of the GPA is 0.67. The Standard Error (S.E.) for all bars is 0.03 and is omitted for clarity
