q2 · i? · causal · r2

Paired samples correlations (Tables 5 and 6) reported for each group's pre- and post-test reading skill: the experimental group's correlation was .990 (n = 31, sig. .000) and the control group's was .63 (n = 30, sig. .041). These are reliability-style correlations between paired measurements, not outcome effect sizes, so no impact magnitude is coded.
