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, post-test scores were significantly higher than pre-test scores (t = 4.8, p < 0.05). → Coşkun and Eker 2018

q2 · i? · causal · r1

Paired comparison of the control group's pre-test (mean 8.03, SS = 3.28) and post-test (mean 13.03, SS = 4.00), n = 30, taught for six weeks with teacher's guidebook, course book and workbook only. The article reports a significant difference and concludes this teaching was "positively efficient in the success of the student".

"The difference between the pre-test and post-test scores of the control group was compared with the t test and it was found there was a significant difference with the value obtained (t = 4.8) and p <0.05)."
