q2 i? Pretest means of the two groups showed no significant difference (t=0.39), supporting group equivalence before instruction. → Tari 2008

q2 · i? · causal · r1

Pretest comparison of the two intact classes (n=15 each) on the 20-item fill-in-the-blank test. Table 4 prints pretest M=6.8 (SD=2.8) for Group A and M=6.4 (SD=2.9) for Group B; the article reports no significant difference, t=0.39, and no effect size.

"Table 4 shows that the means for the two groups on the pretest have no significant difference: t= 0.39, p<0.05. This confirms that the two groups were essentially equivalent before the instruction started."
