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? Control students' scores did not change significantly between pretest and posttest, Mchange = +0.48 (SD = 3.2), t(55) = 1.1, p = 0.27, d = 0.11. → Simon Cullen 2018

q3 · i? · causal · r2

Within-group change in the control condition over the 85-day semester; the article reports a small, non-significant change (d = 0.11), consistent with standard university education producing at best modest analytical-reasoning gains.

"whose scores did not change signi ficantly between the beginning and end of the semester, Mchange =+ 0.48 (SD = 3.2), t(55) = 1.1, p = 0.27, d = 0.11, 95% CI: [ −0.09, 0.31]"
