q3 i3 Among the 15 experimental-group learners, the amount of feedback received showed a strong positive Pearson correlation with post-test score (r = .747). → Nowbakht and Shahnazari 2015

q3 · i3 · causal · r1

Pearson correlation within the experimental group (N = 15) between amount of feedback received during treatment and post-test score; the effect size was r = .747, significant at the 0.01 level (p = .001), leading the authors to reject their null hypothesis.

"The results of the Pearson correlation show that there is a positive correlation (.747) between the amounts of feedback given to each individual learner and his performance in the post-test."
