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? KABC digit-span short-term memory added 4.84% of vocabulary variance beyond book-cover recognition and SON intelligence subtests. → Davidse 2010

q3 · i? · associational · r2
Hierarchical regression Model 3 on vocabulary (N = 174): KABC short-term memory (β = .22) added "an additional 4.84%" of variance after book-cover recognition and SON subtests.
"SON categories accounted for about 4% of the variance, and memory accounted for an additional 4.84%."
