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.

The article reports, citing Pattison, Grodsky, and Muller (2013), that analysis of GPA data from four nationally representative longitudinal samples found "no statistically significant attenuation in the signaling power of grades" and some evidence of an increase. No effect sizes are printed in this article.
"Analyzes GPA data from four nationally representative, longitudinal samples and "do not observe any statistically significant attenuation in the signaling power of grades over this time period. In fact, we find some evidence of an increase in the signaling power of grades.""
Discussion¶
Related Claims¶
- Contextualized high school GPA had a stronger relationship with college success than contextualized standardized test scores (Bastedo et al., attributed)
- On-track improvements were accompanied by across-the-board grade gains, not grade inflation from turning Fs into Ds
