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? Cross-sectional vs. longitudinal design was not significant, though a trend toward higher concurrent correlations was observed; sample type (typical vs. atypical) was also not significant. → Koponen 2017

Koponen, T., Georgiou, G., Salmi, P., Leskinen, M., & Aro, M. (2017). A Meta-Analysis of the Relation Between RAN and Mathematics. Journal of Educational Psychology, 109(7), 977-992. https://doi.org/10.1037/edu0000182
q3 · i? · quant-synthesis · r3
Null results on design and sample-type moderators; no effect sizes printed. The article attributes the sample-type null to heterogeneous atypical populations and states the study "did not provide any evidence that there are differences among these groups."
"Although there was a trend showing that concurrent correlations are higher than longitudinal correlations, the difference was not significant."
Discussion¶
Related Claims¶
- RAN stimulus type (numeric vs. non-numeric; alphanumeric vs. non-alphanumeric) largely does not moderate the RAN–mathematics correlation — related
- Review findings are consistent across study design features; no moderator showed meaningful relationships — related
- RAN correlates more strongly with single-digit than multi-digit calculation and with fluency than accuracy outcomes — related
