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.

q3 i? The CAT improvement was confined to the verbal subscale; there was very little difference between treatment and control groups on quantitative, non-verbal, and spatial elements. → Gorard et al. 2015

q3 · i? · causal · r2

Subscale analysis of the CAT4 gain scores in the same randomised trial, covering the four printed CAT4 reasoning categories (verbal, non-verbal, quantitative, spatial). No subscale effect size is printed in the quoted text, so no magnitude is reported here.

"All of the gain in the CAT scores comes from the verbal subscale. There was very little difference between treatment and control groups in terms of quantitative, non-verbal, and spatial elements of the CAT."
