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? The PBL group's post-test solution quality mean rank (30.12) exceeded the non-PBL group's (20.88), a statistically significant difference. → Z. Abdul Kadir 2016

q2 · i? · causal · r1
Same quasi-experimental pretest–posttest study (n=50, 25 per group). Mann-Whitney U on post-test solution quality: "the value was 20.88" for non-PBL versus 30.12 for PBL; the article reports z = -2.913 and p = 0.004 for quality.
"From the aspect of quality, the mean rank value pres ented was 30.12 for PBL group and for the non-PBL group, the value was 20.88. Thus, it can be concluded that students in PBL group had better quality in their solutions of the problems."
