q2 · i? · causal · r2

Paired samples t-test on the experimental group's (N=22) pretest and posttest writing scores after the 12-week G-DA enrichment program; the article reports t (43) = -9.29, p = 0.000, with no effect size printed.

"Based on Tables 6 and 7, a significant difference was observed between the pretest (M=9.09) and posttest scores (M=13.68) of the experimental group (M= -4.59, SD=2.31), t (43) = -9.29, p = 0.000."
