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? Adding symbolic number variables to models already containing demographics, domain general, and counting predictors significantly increased R2 for fluency (R2 change = .101), computation (R2 change = .099), applied problems (R2 change = .034), and story problems (R2 change = .042). → Martin Rebecca B. 2014

q3 · i? · associational · r2

Hierarchical regression for the fluency outcome showed the symbolic number step added R2 change = .101, p < .001, with "the only significant predictors were the symbolic number variables" plus verbal working memory. Comparable significant R2 changes were reported for the other three outcomes.

"Model 2b added symbolic number variables (symbolic number identification and symbolic number comparison), and the full model showed R2 = .495, R2 change = .101, p < .001. In this model, the only significant predictors were the symbolic number variables (both p < .001)"
