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? Both nonsymbolic and symbolic comparison predicted future mathematical achievement over and above children's IQ and developing working memory capacities. → Xenidou-Dervou 2017

q3 · i? · associational · r2

The longitudinal models controlled for initial IQ and developing Working Memory capacities; the abstract reports "Both skills were longitudinal predictors of children's future mathematical achievement above and beyond IQ and WM." No effect size is printed in the available text.

"Both skills were longitudinal predictors of children's future mathematical achievement above and beyond IQ and WM."
