Subclaims¶

q3 i2 A significant timing × order interaction, F(2, 358) = 26.92, p < 0.001, ηp² = 0.131, superseded the main effect of question order. → Keith B. Lyle 2022 q3 i2 Massing was significantly better on the first question (Hedges' gav = 0.42) and second question (gav = 0.24), but conditions did not differ significantly on the third question. → Keith B. Lyle 2022 (2)

The same within-participants ANOVA on quiz scores (N = 180) revealed a "significant interaction between order and timing" with ηp² = 0.131, superseding the order main effect (ηp² = 0.158).

"Ther e was also a main effect of order, F(2, 358) = 33.67, p < 0.001, ηp 2 = 0.158, but t his was superseded by a significant interaction between order and timing, F(2, 358) = 26.92, p < 0.001, ηp 2 = 0.131."

Bonferroni-corrected paired t tests on each question position (N = 180) showed massed performance "significantly better performance on the first question" (gav = 0.42) and second (gav = 0.24), with no significant difference on the third.

"Massing was associated with significantly better performance on the first question, t(179) = 5.81, p < 0.001, Hedges' gav = 0.42, and second question, t(179) = 3.04, p = 0.003, Hedges' gav = 0.24. The conditions did not differ significantly on the third question, t(179) = 1.33, p = 0.185."
