q4 · i? · design · r2

Moderation analyses within the two randomized cohorts of the Strategic Resource Use intervention; the article reports no statistically significant subgroup differences and interprets this as suggesting "the intervention is equally effective for all of these student groups." No effect sizes are printed for the moderation tests.

"Moderation analyses for Studies 1 and 2 showed that there were no statistically significant differences in the treatment effect between males and females, among students of different racial groups, among students of different class standings, and between low- and high-performing students."
