Subclaims¶

q2 i? In a bivariate regression of overall course score on game choice, the Cooperate coefficient was -9.31 (significant at p < .05). → Byun 2014

q2 i? The difference in mean overall course scores between Cooperators and Non-cooperators was statistically significant at the 5% and 1% levels. → Byun 2014

Evidence¶

Byun 2014¶

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?

Bivariate OLS regression (N = 71) of overall course score on the Grade Game choice dummy, reported in Table 2 with coefficient -9.31 (SE 3.70, *p < .05). The article prints no standardized effect size, so impact is null.

"Based on the fitted line, we predict that a student will score 9.3 points lower overall if he chooses to Cooperate in the Grade Game (significant at the 5% level)."

Discussion¶

Related Claims¶

• Regression predicts Cooperators score 6.7 points lower on the in-class exam, a negative but unemphasized relationship — related
• Non-cooperators were far less likely to score below 70% overall in the course (9.1% vs 38.8% of Cooperators) — related
• The exam-score difference between Cooperators and Non-cooperators was significant only at the 10% level, not the 5% level — related
