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 One-digit subtest scores differed significantly between grades with a large effect (ηp² = .63), with all grades differing from each other. → Brankaer 2017

One-way ANOVA on the full sample (n = 1,588) comparing grades on the one-digit subtest, F(5,1582) = 538.55, ηp² = .63, with Tukey post-hoc tests showing every grade differed from every other. A similar pattern held for the two-digit subtest (ηp² = .57).

"Scores on the one-digit subtest var- ied significantly between the different grades, F(5,1582) = 538.55, p< .01, ηp 2 =. 63 ,a n dT u k e yp o s t - h o ct-tests revealed that all grades differed significantly from each other"
