Note. Two sets of regressions examining effects on post-intervention GPA are presented here. Model 1 displays the in-text reported effects on post-intervention GPA. Model 2 shows these same effects but also includes a baseline covariate (a standardized composite measure of students’ prior semester GPA, ACT, and SAT) that was used in the Harackiewicz, Canning et al. (2014) original study.
