q2 i? Despite a slight difference in pre-test means, the Mann-Whitney U test indicated no significant difference between the experimental and control groups on the pre-test. → Asmalı 2018

q2 · i? · causal · r1

Baseline comparison in the same quasi-experimental study: pre-test means were 48.95 (experimental, n=19) and 42.70 (control, n=24), and the Mann-Whitney U test found "no significant difference" between the groups, so both groups started statistically equal on the 76-question test.

"The results indicated no significant difference between the experimental (Mdn = 50) and the control group (Mdn = 42.10), U = 161.500, p = .103"
