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 · i? · causal · r2

Between-groups comparison of representation quality in a study of 124 eleventh-graders in 39 groups, with classes assigned to conditions. Items were rated on a 0-4 scale with weighted Cohen's kappa of .73; the article reports the GD advantage was significant and that "The corresponding effect sizes (Cohen's d) were large."

"Groups in the GD condition however, made representations of significantly higher quality than groups in the TD condition. This applied to the Martyrs as well as the Propaganda position. The corresponding effect sizes (Cohen's d) were large."
