q2 · i? · causal · r1

Delayed test administered in the fifth week to both groups (EG mean 66.44, SD=20.74; CG mean 64.23, SD=15.81). The study reports "no significant difference" in retention; equivalence was not tested.

"In the delayed tests, the EG ha d a higher retention rate than the CG . However, a two-tailed independent-samples T test (t(60)=.47, p>.05) indicated that there was no significant difference in their performance five weeks after the treatment."
