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? For expository writing quality, among the kindergarten skill predictors only lexical literacy was uniquely related; oral language, attention and letter writing automaticity were not (ps ≥ .18). The kindergarten treatment-status control was negatively related (β = −.23, p = .009). → Kim Young-Suk 2015

q3 · i? · associational · r2

Structural equation model for expository writing quality in the same longitudinal sample (N = 157), with good fit (CFI = .95; RMSEA = .055). The quote shows oral language was not uniquely predictive; no effect size was printed for the null paths. The article adds one exception among the controls: kindergarten treatment status was negatively related to expository writing quality (β = −.23, p = .009).

"As shown in Figure 2, only kindergarten literacy skill was related (β = .43, p < .001) whereas the other predictors were not (ps ≥ .18)."
