q2 · i? · associational · r1

Same balanced Codeforces comparison of 908 active vs 908 true attrition users. The article reports the struggle-time increase as directionally consistent with the progress stagnation hypothesis but that it "does not reach statistical significance" (p= 0.213, ns); no effect size is printed.

"The 15.6% increase in mean struggle time (p= 0.213,ns) is directionally consistent with the progress stagnation hypothesis but does not reach statistical significance."
