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? Higher trait self-control predicts higher major GPA (β = 0.07, p = 0.008) after controlling for fluid reasoning, conscientiousness, gender, age, HISEI, and migration status. → Schmidt FTC 2020
Evidence¶
Schmidt FTC 2020¶
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
Simultaneous multivariate multiple regression in Mplus with cluster-robust standard errors on N = 3,146 vocational trainees; Table 2 prints the TSC slope for mGPA as 0.07 [0.02, 0.11], p = 0.008, showing "higher trait self-control was associated with higher mGPA".
"On average, higher trait self-control was associated with higher mGPA but not with higher test scores in mathematics and physics."
