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.

q3 i2 A significant time x group interaction on the Trait Sport-Confidence Inventory indicated the experimental group improved self-confidence while the control group did not change meaningfully. → Miçooğullari and Kirazci 2016

q3 · i2 · causal · r1

Mixed design ANOVA on TSCI scores across five measurements in the two-team quasi-experiment; the article reports the interaction (η2 = .11), time (η2 = .28), and group (η2 = .45) effects all significant at p < .05, with the experimental group showing positive self-confidence implications.

"A time x group interaction was found to be significant, F (2.40, 81.57) = 4.34, p < .05 η 2 = .11. Test of time effect was found to be significant, F (2.40, 81.57) = 13.21, p < .05 η2 = .28. Test of group effect was found to be significant, F (1, 34) = 32.09, p < .05 η2 = .45."
