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 studies using both instruments, LSAT logical reasoning effect sizes were three times smaller than CCTST effect sizes; the article attributes this partly to low psychometric quality of the CCTST. → Simon Cullen 2018

q2 · i? · causal · r2

The discussion attributes this discrepancy to prior studies (citing refs 26–27), noting the review-level claim that the CCTST "exhibits low internal consistency and poor construct validity" while LSAT forms show high reliability.

"In recent studies where students completed both LSAT logical reasoning and CCTST forms, effect sizes were three times smaller with the LSAT than they were with the CCTST"
