q2 · i? · causal · r1

Paired t-tests run in SPSS on pretest-posttest scores for each of the four classes, after Kolmogorov-Smirnov normality checks returned p = 0.200 for both universities. The article reports "p-value of t-test statistics for all paires ... was 0.000 (<0.05)"; no effect size is printed.

"The Table 4 informs that the significance (2-tailed) or p-value of t-test statistics for all paires (pretest and posttest) on Class A, B, C, and D was 0.000 (<0.05)."
