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 i? In Experiment 1, ratio effect scores correlated with mathematics test performance (r = .544), but in Experiment 2 there was no relationship between ratio effect scores and mathematics achievement (r = .007, n.s.). → Gilmore Camilla K. 2010

q3 · i? · associational · r2

Experiment 2's analysis of ratio effect scores used easier comparison ratios (5:7, 5:8, 5:9) that all should elicit above-chance performance, unlike Experiment 1 where children performed at chance on the most difficult ratio. The authors conclude students across the achievement spectrum focused on number.

"In contrast to Experiment 1, there was no relationship between children’s ratio effect scores on the non-symbolic addition task and their achievement in mathematics (r = .007, n.s.)."
