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? After the treatment, the experimental group scored significantly higher than the control group on the Mathematics post-test. → Olu Oyinloye 2013

q2 · i? · causal · r2

Mathematics post-test in the same quasi-experiment: experimental mean 11.800 (SD 1.98) versus control mean 10.769 (SD 1.45), with t-cal "-6.08" against a table value of 1.96, reported as a significant difference at 0.05. The table itself prints -6.38, an inconsistency in the article.

"Table 4 above shows that the t-cal is -6.08 while the table value is 1.96. This implies that the t-calculated is greater than the table value. The null hypothesis is therefore retained at 0.05 level of significance. This implies that the achievement of the students in the experimental group in Mathematics is significantly different from that of the control group."
