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 i3 Attitude scores rose significantly (Wilcoxon z = -4.875, p = .000) from a constant pretest of 80 to a posttest median of 83.3, with the article reporting effect size 0.629 as a high effect size. → Hanafi 2016

Evidence

Hanafi 2016

Hanafi. (2016). The Effect of Discovery Learning Method Application on Increasing Students' Listening Outcome and Social Attitude. Dinamika Ilmu, Vol. 16 No. 2. https://portal.issn.org/resource/ISSN/1411-3031

q2 · i3 · causal · r1

Observed social-attitude data from the same one-group study, 31 valid samples; all pretest scores were 80. Posttest median 83.3. The article reports "the effect size of 0.629 indicates that the treatment given to the students has a high effect size".

"Analysis results by Wilcoxon Signed Rank test on table 11 above shows that the level of significance is 0.000. This number is smaller than 0.05, meaning that there is a significant increase in the value of the pre -test to post-test score"
