q2 · i? · causal · r1

Paired samples t-tests comparing pre and post scores for each group; the experimental t-value was 4.91 and the control t-value 17.41, both with p < .05, and the article states "students gained from both approaches" but the experimental group showed a higher mean improvement.

"the mean score difference between the post test and pre test of the experimental group was 9.50 as compared to the control group with 4.36."
