Byun, C.H.C. (2014). The Prisoner's Dilemma and economics 101: Do active learning exercises correlate with student performance? Journal of the Scholarship of Teaching and Learning, 14(5), 79-91. https://doi.org/10.14434/josotlv14i5.12950

q2 · i? · associational · r1

Difference-of-means t-test on the in-class exam (the exam including Game Theory) for the same 71 students. The article reports t = -1.73 with p = 9.4%; no effect size is printed, so the finding is marginal.

"For the in-class exam scores, the calculated t-statistic was -1.73, with 27 degrees of freedom. The associated p-value was 9.4%, indicating that the test statistic was significant at the 10% level, but not the 5% level."
