q2 i3 The hierarchy group (M = 86.67) significantly outperformed the copying group (M = 60.17) on the reading comprehension test, t(49.111) = 5.073, p < .05, with a large effect size d = 1.35. → Lin 2013

q2 · i3 · causal · r2

Reading comprehension test (multiple-choice format) administered after the treatment with 56 Grade 5 EFL students. Independent t-test showed the hierarchy-exercise group scored significantly higher, with the article reporting "The effect size was defined as being large (d = 1.35)".

"First, the mean of the experimental group (M = 86.67, SD = 15.44) was higher than that of the control group (M = 60.17, SD = 23.13). A significant difference was found between the two groups (t (49.111) = 5.073, p < .05). The effect size was defined as being large (d = 1.35)."
