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 pretest ANOVA found no statistically significant difference between the groups. → Celal Boyraz 2017

q3 · i? · causal · r1
One-way ANOVA on the 15-item achievement pretest administered before the five-week treatments; the article reports F(3,78)=0.469, p>.05, and treats the groups as equal in prior knowledge of the force unit. Equivalence was not formally tested.
"there was no statistically significant difference between the groups based on the achievement pretest, F(3,78)=0.469, p>.05."
