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? Age in months positively predicted both CVS scores, while gender related to neither score. → Joep van der Graaf 2015

Evidence

Joep van der Graaf, Eliane Segers, Ludo Verhoeven. (2015). Scientific reasoning abilities in kindergarten: dynamic assessment of the control of variables strategy. Instr Sci 43:381–400. https://doi.org/10.1007/s11251-015-9344-y

q2 · i? · associational · r2

Linear regression models with gender and age in months entered simultaneously as independent variables and the experiment or variable correct scores as dependent variables, in 45 kindergartners. Age was a positive predictor of both scores; gender was unrelated to either.

"Age related positively to both the experiment correct scores, b = .51, p\ .001, and the variable correct scores, b = .47, p = .002. Gender did not relate to either the experiment correct scores, p = .469, or variable correct scores, p = .314."
