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 full regression model explained 29% of mathematics and 37% of physics test variance but only 12% of mGPA variance. → Schmidt FTC 2020

Evidence

Schmidt FTC, Lindner C, Etzel JM and Retelsdorf J (2020) Self-Control Outdoes Fluid Reasoning in Explaining Vocational and Academic Performance—But Does It? Front. Psychol. 11:757. https://doi.org/10.3389/fpsyg.2020.00757

q3 · i? · associational · r3

Multivariate regression on N = 3,146 trainees; the printed R² values were 0.29 (math), 0.37 (physics), and 0.12 (mGPA), and "the constructs explained substantially more variance of the achievement tests" than of grades.

"Combined, the constructs explained substantially more variance of the achievement tests (math, 29%; physics, 37%) than they did for mGPA (12%)."
