q2 · i? · causal · r1

Pretest-posttest control group experiment (N=8, four per group, randomly assigned); experimental group practiced newly written etudes for two weeks while the control group practiced the pieces. Table 3 reports Mann–Whitney U posttest p-values (e.g., TMV-post p = 0,004) favoring the experimental group; the text states the "evaluation scores of the experimental group were higher than the evaluation scores of the control group."

"On the other hand, when the posttest characteristics of the groups were examined, it was observed that the evaluation scores of the experimental group were higher than the evaluation scores of the control group. The data show that the etudes applied to the experimental group between the pre-test and the posttest were successful in all the pieces."
