q3 i? A Mann-Whitney U test found no significant difference between the groups' pre-test scores (z=-0.34; p=0.734), supporting group comparability at baseline. → Ahmet Başal 2016

q3 · i? · causal · r2

Mann-Whitney U comparison of pre-test scores in the quasi-experiment (control mean 12,89±7,66; experimental 11,97±6,62; z=-0,34; p=0,734 per Table 2). Equivalence was not separately tested beyond this non-significant result.

"Based on this test, no significant difference was found between the pre-test scores of both groups (Table 2)."
