Subclaims¶
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.
q2 i? Within the control group, pre- to posttest completion time improved significantly (t(13) = 3.60, p < .025), whereas the treatment group's change in completion time was not significant (t(13) = 1.50, p > .025). → Letwinsky 2017

q2 · i? · causal · r1
Repeated measures MANOVA with paired t-tests (Bonferroni-adjusted alpha of .025) on within-group pre/post changes. The article reports the treatment group's time change was not significant (t(13) = 1.50, p > .025); no effect size is printed, so impact is unquantified.
"the control group reached statistical significance on pre- and posttest scores (t(13) = -3.41, p < .025) and also was significant on pre- and posttest time (t(13) = 3.60, p < .025)."
