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 the PISA 2000 total sample, the mean decrease in within-domain effects in the difference I/E model was ∆B = –.026 (∆β = –.033) after specifying the achievement difference as a predictor. → Fabian Wolff 2026

q2 · i? · associational · r?
Reanalysis of PISA 2000 total sample (N = 55,582) comparing changes in within-domain effects across the two I/E model specifications. The authors report "a mean increase in the within-domain effects in Model 2 of ∆B = .059 (∆β = .073), whereas the mean decrease in the within-domain effects in Model 3 was only ∆ B = –.026 (∆β = –.033)."
"we found a mean increase in the within-domain effects in Model 2 of ∆B = .059 (∆β = .073), whereas the mean decrease in the within-domain effects in Model 3 was only ∆ B = –.026 (∆β = –.033)"
Discussion¶
Related Claims¶
- Within-domain effects in the classic I/E model increase after controlling for between-domain effects when the latter are negative, consistent with them reflecting between-domain achievement effects — related
- Stronger between-domain effects in the I/E model versions are associated with stronger changes in within-domain effects after controlling for the between-domain effects — related
- Within-subject achievement effects in the classic I/E model confound social and dimensional comparisons; using the math–verbal achievement difference as predictor isolates each comparison type — related
