Subclaims¶

q2 i? Institution-wide undergraduate average GPA rose by 0.07 between 2008 and 2011, less than the reported 0.11 and 0.12 differences, so grade inflation cannot fully account for the gains. → Robinson 2021

q2 · i? · associational · r2

Descriptive comparison of University of Texas at Austin undergraduate average GPA across the two cohorts, examining the history threat to internal validity. The 0.07 rise "could partly explain the GPA differences between the 2008 and 2011 students, it cannot fully account for the differences".

"The actual difference between undergraduate average GPA in 2011 compared with 2008 is 0.07 (3.27 − 3.20). This difference, however, is considerably less than the differences in GPAs reported by Pennebaker et al. ( 2013) of 0.11 and 0.12."
