Subclaims¶

q3 i2 Quiz performance was overall worse when questions were spaced (M = 0.78) versus massed (M = 0.81), with a main effect of timing, F(1, 179) = 9.64, p = 0.002, ηp² = 0.051. → Keith B. Lyle 2022

Completely within-participants 2 (timing) × 3 (question order) ANOVA on quiz scores from the same calculus course experiment (N = 180) showed "performance was overall worse when questions were spaced" with ηp² = 0.051.

"There was a main effect of tim- ing, F(1, 179) = 9.64, p = 0.002, ηp 2 = 0.051, suc h that, as anticipated, performance was overall worse when questions were spaced (M = 0.78, SD = 0.13) versus massed (M = 0.81, SD = 0.13)."
