q2 · i? · associational · r1
Post-hoc Tukey tests following the one-way ANOVA compared the three class sizes; the smallest class differed significantly from both larger classes, but the 10- and 15-student classes did not differ significantly from each other. No effect size is printed.
"Post-hoc comparison using the Tukey test indicated that the mean score for class A was significantly different from class B and class C; however, Class B and class C did not differ significantly from each other."
