Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i3 MANCOVA revealed a statistically significant multivariate effect of condition on the combined outcomes, with approximately 18.5% of variance attributable to condition after adjusting for baseline. → Mahir Akgun and Sacip Toker 2026

q3 · i3 · causal · r2

MANCOVA on data from 89 undergraduates (G1: n = 27; G2: n = 28; G3: n = 34) in an applied statistics course, with baseline as covariate. The article reports "Wilks’Λ=.664" and "partialη2 =.185". Pretest performance did not significantly predict the combined outcomes (p = .918).

"MANCOVA revealed a statistically significant multivariate effect of condition,Wilks’Λ=.664,F(4,168) = 9.56, p < .001, partialη2 =.185, indicating that approximately 18.5% of the vari- ance in the combined outcome space was attributable to condition after adjust- ing for baseline."
