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.
q3 i? The experimental group's performance on the delayed post-test did not differ significantly from its immediate post-test performance, so the second null hypothesis was confirmed. → Negari 2018

q3 · i? · causal · r1
Paired samples t-test on the experimental group (n=23) comparing immediate post-test and delayed post-test administered three weeks later. The article reports the difference was "not statistically significant , t (22) = .21, p >.05"; equivalence was not tested.
"the difference between the participants’ performance on the post -test (M= 9.57, SD=2.59) and the delayed post -test (M=9.39, SD, 2.25) was not statistically significant , t (22) = .21, p >.05."
