q2 · i? · causal · r1

Paired sample t-test on first-draft scores in the 44-student two-group experiment. The article reports no significant difference at baseline; equivalence was not formally tested beyond this comparison, and no effect size is printed.

"For pair 1 (Draft 1 between the control and experimental groups), the p value is .830 (p>.05). This indicates that there is no significant diff erence in the performance of both the control and experimental groups."
