q3 i? Between-group heterogeneity by application type was not statistically significant (Q = 0.001 below the critical value of 3.841); class-based and selected-student applications had nearly identical point estimates. → Fulya Turk 2017

Evidence¶

Fulya Turk 2017¶

Fulya Turk. (2017). Evaluation of the Effects of Conflict Resolution, Peace Education and Peer Mediation: A Meta-Analysis Study. International Education Studies; Vol. 11, No. 1. https://doi.org/10.5539/ies.v11n1p25

q3 · i? · quant-synthesis · r2

Moderator analysis comparing applications delivered to selected students (12 studies, g = 1.245) versus whole-class delivery (11 studies, g = 1.253). The difference was not statistically significant (Q = 0.001 < 3.841).

"the effect size of the applications carried out as a class (g= 1.253) is greater . However, the difference between the effect sizes is not statistically significant since the Q=0,001 value is below the critical value of 3.841"
