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? Posttest PÖÖ2 mean scores differed significantly between experimental and control groups in favor of the experimental group (6.31 vs 3.39). → Seval Deniz KILIÇ & Hüseyin ALKAN 2018

q2 · i? · causal · r1

Semi-experimental pre-test post-test control-group study with 29 students per group in an Anatolian high school; t-test on PÖÖ2 posttest means gave t = 5.959, p = 0.000, with means of 6.31 (experimental) and 3.39 (control), showing "a statistically si gnificant difference".

"As can be seen in Table 4, there is a statistically si gnificant difference between the PÖÖ2 mean scores of the experimental and control groups. This difference is in favor of the experimental group."
