q2 i? There was no significant difference between the groups' pretest scores (t(36)=-1.21; p>0.05), supporting group equivalence at baseline. → Akçay 2016

q2 · i? · causal · r1

Baseline comparison from the same semi-experimental pretest-posttest study (JG N=20, CG N=18). The pretest t-test found "no significant difference between them (t(36)=-1.21; p>0.05)"; equivalence beyond the non-significant test was not tested.

"it was determined that the arithmetic mean of the pretest results of the experimental group was 1.70 and standard deviation was 1.34; the arithmetic mean of the control group was 2.22 and the standard deviation was 1.30, and there was no significant difference between them (t(36)=-1.21; p>0.05)"
