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? In the parent-led dialogic reading group versus a group story-time comparison (n = 19), neither the authors nor the WWC found statistically significant differences on any communication or language measure. → Dialogic Reading 2010

q3 · i? · quant-synthesis · r1

Randomized controlled trial comparing parent-implemented dialogic reading with a group story time comparison among 19 three- to five-year-olds with mild to moderate language delays. "The WWC did not find statistically significant differences on any measure"; the study's average effect size was 0.11, not significant, and average improvement index +4.

"The authors did not find statistically significant differences between the parent-led intervention and the comparison group on any of the measures. The WWC did not find statistically significant differences on any measure"
