Fig. 2From: STEM courses are harder: evaluating inter-course grading disparities with a calibrated GPA modelObserved GPA plotted against unweighted calibrated GPA (left panel, Equation (6) and weighted calibrated GPA (right panel, Equation (7)) for each student. The right panel shows that using the weighted calibrated GPA almost completely eliminates the overestimation that is visible in the left panel for the original unweighted calibrated GPABack to article page
