From: STEM courses are harder: evaluating inter-course grading disparities with a calibrated GPA model
Average grading difference between general education and gateway courses within ten STEM departments. A grade difference of 1.0 is equivalent to a letter grade. Positive values indicate that the gateway course was graded more stringently than the general education course. Open squares represent the grade offset calculated using the observed GPA. Black squares represent the grade offset calculated using the calibrated GPA. Error bars display ± 1 S.E. Diamonds are the weighted average of the ten departments
