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? In the full polynomial model, both the linear and quadratic terms of autonomous motivation positively and significantly predicted grades, indicating an accelerating rate of increase. → Mouratidis 2021

Mouratidis, A., Michou, A., Sayil, M., & Altan, S. (2021). It is autonomous, not controlled motivation that counts: Linear and curvilinear relations of autonomous and controlled motivation to school grades. Learning and Instruction, 73, 101433. https://doi.org/10.1016/j.learninstruc.2020.101433

q3 · i? · associational · r2

Sample 1 full polynomial regression: autonomous motivation squared was a significant positive predictor (b = 1.95, p < .01, from Table 2). In Sample 2, autonomous motivation squared also predicted grades (b = 1.94, p = .044). Both samples' surfaces were mildly convex with highest estimated grades at high autonomous and low controlled motivation. No standardized effect size is printed for the quadratic term.

"In that model both the linear and curvilinear relations of autonomous motivation to grades were positive and statistically significant. This finding suggests an accelerating rate of increase in grades"
