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? Only three published studies have examined meditation and academic achievement; the review concludes insufficient evidence has accumulated to answer the effectiveness question for this outcome. → Lea Waters 2015 q2 i2 Nidich et al. (2011) reported strong significant improvements in English and Math California Standards Test scores for 125 students after 3 months of twice-daily 12-min TM practice versus a randomly assigned control group (composite d=.79, math d=.85, English d=.44). → Lea Waters 2015 (2)

The review's summary of the academic achievement literature: only three studies exist, two using standardised tests and one using student self-assessments; effect sizes were calculable for two studies, with Cohen's d ranging from 0.44 to 0.83.

"In summary, research into school meditation programmes is still in its infancy, and only three published studies have examined the relationship between meditation and academic achievement."

The review reports this non-random experiment trial (Table 2 lists it as non-random experiment trial). Table 3 prints the effect sizes: composite d=.79, math d=.85, English d=.44 (dIGPP, SDpost). The review attributes the finding to Nidich et al. (2011).

"Nidich et al. (2011) reported strong significant improvements in English and Math scores on the California Standards Test for 125 sixth- and seventh-grade students who underwent 3 months of twice daily (i.e. before and after school) 12-min TM practice in comparison to a randomly assigned control group."
