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.

q4 i2 Conscientiousness correlations are larger for grades (ρ = 0.28) than for test scores (ρ = 0.13). → Meyer 2023 q4 i2 The grades-over-test-scores pattern holds within STEM (ρ = 0.26 vs. 0.11) and language (ρ = 0.27 vs. 0.16) domains, with no significant domain × measure interaction. → Meyer 2023 (2)

q4 · i2 · quant-synthesis · r2

Meta-analysis of 305 conscientiousness effect sizes from 74 studies (N = 513,300), corrected for measurement error, found "larger correlations found for grades (ρ = 0.28) compared to test scores (ρ = 0.13)"; the domain moderation itself was not significant (p = 0.230).

"we did find a moderating effect of measure (RQ2), with larger correlations found for grades (ρ = 0.28) compared to test scores (ρ = 0.13; z = 5.17; p < 0.001)"

q4 · i2 · quant-synthesis · r2

In the individual domain × measure comparisons, grades exceeded test scores within both named domains; the overall interaction was not significant (t[60] = 1.58; p = 0.119), and no domain differences emerged within either measure.

"we found larger correlations of grades compared to test scores with both STEM (ρ = 0.26 vs. 0.11; z = 4.54; p < 0.001) and language subject domains (ρ = 0.27 vs. 0.16; z = 3.27; p = 0.001)"
