q2 · i? · causal · r1

Quasi-experimental baseline check comparing the two intact classes on previous-semester science scores; an independent-samples t-test "showed no significant differences between the two classes". Equivalence was not further quantified and no effect size is reported.

"Prior to the intervention, the two classes were compared in terms of science learning ability and knowledge base on the basis of their science scores from the final examination of the previous semester. An independent-samples t-test showed no significant differences between the two classes."
