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? There was no significant difference between the two focus groups in grades average at the initial test (experimental A=4.21, control A=4.19). → Monica-Iuliana Anca & Muşata Bocoş 2017

q2 · i? · causal · r1
Pre-test comparison using the t test for independent focus groups after a Levene test accepted variance homogeneity; averages were 4.21 (experimental, n=84) and 4.19 (control, n=81). Equivalence beyond the non-significant test was not tested.
"Whereas p>α (0.05), the H0 hypothesis is accepted, meaning there are no significant difference between the two focus groups in what concerns the grades average values at the initial test."
