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 · associational · r2

Preliminary correlation analysis of the pooled IPD meta-analysis dataset. Achievement changes were calculated as differences between end-of-period and start-of-period achievements; the printed correlation is "r = .26, p < .001".

"Students' math and verbal achievement changes also showed a positive correlation (r = .26, p < .001)."
