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.
q3 i2 After two weeks of instruction, the mastery learning group's mean post-test score (78.2) exceeded the control group's (58.4) by 19.8 points, a highly significant difference with a substantial effect size of 0.60. → Telimoye Leesi Mitee and Georgina N. Obaitan 2015

q3 · i2 · causal · r2
Quasi-experimental control group study: four schools randomly assigned, 207 mastery learning students and 194 controls, two weeks of treatment, independent sample t-test on a 25-item chemistry achievement test. The article reports "The effect size is 0.60" and t(399) = 14.92, P<0.05.
"The mean score in the post-test for mastery learnin g group was 78.2% and the standard deviation was 9.90 and the mean score in the post-test for contro l group was 58.44% and the standard deviation was 1 6.07"
