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? Neither the WRMT-R word comprehension subtest (ES 0.41) nor the passage comprehension subtest (ES 0.28) showed a statistically significant SMART® effect, but the domain-average effect size of 0.35 met the WWC's substantively important threshold of at least 0.25. → What Works Clearinghouse 2007

q3 · i? · causal · r?

In the randomized controlled trial's comprehension domain, the word comprehension subtest showed ES 0.41 and passage comprehension ES 0.28, both marked ns; the domain average of 0.35 was judged substantively important, with an average improvement index of +14 percentile points (Appendix A3.3).

"The WWC did not find that either of these effects was statistically significant. The average effect size across the two outcomes, however, was large enough to be considered substantively important according to WWC criteria (that is, an effect size of at least 0.25)."
