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 · i2 · causal · r2

Survey-based outcome from a five-cohort cluster-randomized trial (267 students, 152 teachers, 45 rural schools), analyzed with three-level multilevel models and FDR-adjusted p-values. The Time x Condition interaction favored CBC, with "d = -.45"; the article notes the average CBC participant outgained about 67.35% of control participants.

"A significant Time x Condition interaction [γ = -2.09, t (176) = -2.71, p = .05, d = -.45] favoring the CBC group indicates that improvement in academic difficulties (e.g., attention problems, learning problems) among students assigned to receive CBC significantly outpaced that of students experiencing business as usual on average"
