q2 · i? · causal · r2

Dependent samples t-test on the control group's essays (n=48), scored with the Writing Expression Evaluation Scale, in this pretest-posttest quasi-experiment. The article reports "a significant difference between these two scores" and concludes achievement decreased in the control group.

"the control group pre -test mean score was 51.22, and the posttest mean score was 47.12. It was observed that there was a significant difference between these two scores [t(47) = 2.041; p <.05]"
