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? At-risk students receiving graduation coaching performed almost an entire letter grade better in core courses than similar at-risk students in baseline cohorts. → Zeller 2013

q3 · i? · causal · r1

Causal-comparative analysis of 32 coached at-risk 9th graders versus 100 uncoached at-risk baseline students, using core-course GPA as the outcome. The planned contrast showed coached students "performed almost an entire letter grade better than expected" (Wald χ2 = 47.31, p < .0001).

"Coached students performed almost an entire letter grade better than expected based on comparative student results from baseline studies (Wald χ2 df=1 = 47.31, p < .0001)."
