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 Across near transfer, far transfer, calculation and the two recall variables, giftedness produced a significant multivariate main effect with η2 p = .178, a large multivariate effect size. → Lim 2023

q3 · i3 · causal · r2

Multivariate ANOVA in the Results section of the randomized study of 199 seventh graders, with instruction, contrast and giftedness as independent variables and five dependent measures. The article reports a significant multivariate main effect for giftedness with the printed effect size η2 p = .178, along with Wilks' λ = .822, F (5, 186) = 8.08, p < .001.

"The multivariate ANOVA revealed a significant multivariate main effect for the dependent variables col- lectively for giftedness (Wilks' λ = .822, F (5, 186) = 8.08, p < .001, η2 p = .178)"

Discussion¶

Learner Variables¶

General Cognitive Ability — predictor: learners who differ on it differ in outcomes
