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? In a reanalysis of PISA 2000 data across 26 countries, within-domain effects in the classic I/E model increased after adding achievement in the other domain as a predictor when between-domain effects were negative. → Fabian Wolff 2026

q2 · i? · associational · r2

Reanalysis of PISA 2000 data (N = 55,582 students from 26 countries) comparing classic and difference I/E model specifications using manifest constructs in Mplus 7. The authors report that "we found increases in the within-domain effects in Model 2 as well as decreases in Model 3 in all analyses if the between-domain effects in the classic I/E model were negative."

"As hypothesized, we found increases in the within-domain effects in Model 2 as well as decreases in Model 3 in all analyses if the between-domain effects in the classic I/E model were negative."
