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.

q2 i? Word semantic, simple subtraction, and complex subtraction significantly predicted Grade 9 entrance examination mathematics, accounting for 4.4%, 5.4%, and 5.4% of variance. → Cheng Dazhi 2022

q2 · i? · associational · r2

Longitudinal follow-up regression: cognitive tests administered at the start of Grade 7 predicted high school entrance examination mathematics at the end of Grade 9, after controlling for age, gender, and general cognitive abilities. The specific speed measures "accounted for 4.4%, 5.4% and 5.4% of the variances" in entrance examination mathematics, a span the authors describe as three years. The design is correlational, so prediction here is statistical, not causal.

"In the 9th grade, specific processing speed including word semantic, simple subtraction, and complex subtraction could predict mathematical achievements, and they accounted for 4.4%, 5.4% and 5.4% of the variances in mathematical achievement in the high school entrance examination."
