q3 i? Control students scored higher on the pretest (M = 17.4 vs M = 15.9), but the difference was not statistically reliable, t(114) = 1.4, p = 0.152. → Simon Cullen 2018

q3 · i? · causal · r2

Baseline check on the equivalated LSAT pretest administered to both groups at semester start. The article reports means and a d = 0.27 pretest difference that was "nor statistically reliable"; equivalence was not tested.

"Pretest scores were higher in the control group (M = 17.4) than in the seminar group ( M = 15.9), however this difference was neither large ( d = 0.27) nor statistically reliable, t(114) = 1.4, p = 0.152"
