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 i? A two-way ANOVA found little evidence that student retention performance varied by class hour, while the treatment effect remained significant. → Lindquist 2024

q3 · i? · causal · r2

Two-way ANOVA (treatment/control by hour of day) on retention index in the USMAPS experiment; Table 4 reports hour effect p = 0.093 and C vs. T p = 0.021. The article suggests the null hour effect may reflect a required morning accountability formation for all students. No effect size is printed.

"To explore this influence, we conducted a two-way ANOVA and found that there is little evidence to suggest that in this experiment student performance varied by class hour (see Table 4)."
