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? The mean WWC improvement index for the prosocial domain was +23 percentile points; teacher-reported ABI and SSiS social skills were +31 and +28. → Feil 2014

q3 · i? · causal · r2

WWC improvement index computed from effect sizes for each outcome. Teacher-reported ABI and SSiS social skills scores were +31 and +28 percentile points; parent-reported social skills was +11. Problem behavior domain mean was +24 percentile points.

"With respect to the prosocial behavior domain, the mean improvement index score was +23 percentile points (i.e., an average control student receiving the intervention would be predicted to have a mean improvement of 23% on social skills outcomes)."
