q3 · i? · causal · r2

Subgroup analysis of the same RCT (not summer enrolled N = 1,471): treatment effect 0.037 (OR 1.16), control mean 0.543, not statistically significant; equivalence was not tested.

"Although we observed a difference of nearly 4 percentage points in the predicted direction among students not enrolled in summer courses, this effect failed to reach statistical significance."
