q2 i? The experimental group's mean rose from M=40.34 (SD=17.32) on the pretest to M=48.86 (SD=18.38) on the posttest, a significant paired difference (t=-4.372, df=28, p=.000). → Karaazmak 2018

q2 · i? · causal · r1

Paired samples t-test within the experimental group (n=29) comparing pretest and posttest grammar scores; the article reports a significant difference with t=-4.372, df=28, p=.000 in Table 2. No effect size is printed.

"there is a significant difference ( p<.05) between the mean scores of the first ( M=40.34, SD=17.32) and second grammar test (M=48.86, SD=18.38) of the experimental group."
