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? Of the effect sizes calculated across 15 peer-reviewed school meditation studies, 61% were statistically significant, with 67% small, 24% medium and 9% large effects. → Lea Waters 2015

q3 · i? · quant-synthesis · r1
The review's own synthesis of 15 peer-reviewed studies of school meditation programmes, with effect sizes computed as Cohen's d in Comprehensive Meta-Analysis software. The results section states "a total of 762 effects of which 61 % were significant"; the abstract reports 76 effect sizes from 1,797 participants, an internal inconsistency in the article.
"Each study provided between 1 and 17 effects for a total of 762 effects of which 61 % were significant."
Discussion¶
Related Claims¶
- Evidence on meditation and academic achievement is scant: only three published studies, with the strongest from TM programmes on standardised test scores — related
- Among live-evaluation RL-in-education papers reporting significant differences, a majority reported at least one intermediate (n = 5) or large (n = 6) Cohen's d effect on post-test learning outcomes — related
