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? Pre-test scores did not differ significantly between groups (t = 1.6, p = 0.11), supporting group comparability. → Coşkun and Eker 2018

q2 · i? · causal · r2
Independent-samples t test on pre-test scores of 30 experimental and 30 control ninth graders; Table 5 prints means of 9.63 and 8.03, t = 1.6, p = 0.11. The article concludes the groups were "similar in terms of academic achievement scores before the experiment".
"At the end of pre-testing of the groups, t test was used to determine whether there was a significant difference between the scores obtained and it was found that there was no statistically significant difference with the value obtained [p <0.05]."
