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.

q2 i? Word semantic, simple subtraction, and complex subtraction each accounted for significant unique variance in Grade 7 mathematics (5.6%, 7.2%, and 5.1% respectively). → Cheng Dazhi 2022

q2 · i? · associational · r2

Hierarchical regression analysis of 212 junior high students tested at the start of Grade 7, controlling for age, gender, nonverbal matrix reasoning, spatial abilities, and visual attention. The article reports that these specific speed measures "accounted for 5.6%, 7.2%, and 5.1% of the variances in mathematics" with Bonferroni-corrected significance.

"Word semantic, simple subtraction, and complex subtraction accounted for 5.6%, 7.2%, and 5.1% of the variances in mathematics."
