q3 i3 An ANOVA showed exam scores differed significantly across the four quartile groups (F(3, 478) = 1174.49, η² = 0.88), with each group's mean significantly higher than the next in the expected order. → Hou 2025

The 482 students were divided into quartiles by first-unit exam score (high n = 123, mid-high n = 122, mid-low n = 116, low n = 121); the ANOVA found "statistically significantly different" scores, η² = 0.88, and Tukey tests confirmed each group exceeded the next in order.

"An analysis of variance (ANOV A) indicated that the exam scores for the four quartile groups were statistically significantly different from each other (F(3, 478) = 1174.49, p <.001, η 2 = 0.88)"
