q2 · i? · causal · r1

Wilcoxon test within the experimental group (n=3); descriptive means increased from 9.00 to 17.22, but the article reports the change was not statistically significant and prints no effect size. This qualifies the between-group post-test finding.

"As can be seen in Table 6, according to the results obtained, no statistically significant difference was obtained between pre- and post- test results of experimental group in viola playing skills (z=-1.604; p>0.05)."
