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? Of 531 effect estimates, 320 are null at 90% CIs, 168 positive, and 43 negative. → Shakeel 2024

q3 · i? · quant-synthesis · r3

Descriptive distribution of all 531 coded effect sizes (Fig. 2 and Results text), classified by 90% confidence intervals. The authors interpret this varied distribution as suggesting "an overall positive effect may be observed when RVE is used to cluster the effects within databases."

"The distribution of the estimates of the effects of private schooling on civic outcomes, based on 90% confidence intervals, yields 168 positive, 320 null, and 43 negative findings (Fig. 2)."
