Evidence quality · No study behind this claim is a peer-reviewed article with a DOI: it rests on a source with no registered publication record (a web page, book or unpublished report). It is kept because 2 design pages cite it; treat it as a lead to check, not an established finding.
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? Mantel-Haenszel DIF analysis flagged four items, but differential response times alone did not predict which items would be DIF-flagged. → Srdjan Verbić & Boris Tomić 2008

q2 · i? · associational · r1
Mantel-Haenszel DIF procedure (items with p<0.05 flagged) applied to the boys-versus-girls comparison on the 32-item physics test. Appendix Table 2 lists the flagged items, yet response-time differences did not anticipate the flags.
"We have found DIF for four items but we could not anticipate which item would be DIF flagged on the basis of differential response times only."
Discussion¶
Related Claims¶
- The ICC and LDF methods identify substantially different sets of items as exhibiting DIF on a state science performance assessment — the general claim this finding bears on, with the studies behind it
- Boys responded faster than girls on the test, but the response-time difference did not affect achievement — related
- Mean response likelihood does not differ significantly between boys and girls, but its variance is 1.46 times greater for girls — related
- Boys and girls do not differ in the type of mental models of the day and night cycle they hold — related
- The negative response time–likelihood trend holds for boys (R=-0.22) but not for girls (R=+0.04) — related
- Differential item functioning was found in four items across the function, form and level dimensions — related
- Most Spanish test items show negligible differential item functioning across gender and Hispanic–White comparisons — related
