q2 i? Combining the $46.23 per-participant cost with the 0.10 SD effect yields an approximate cost of $462.30 per student per standard deviation difference on the long-term EOG math assessment. → Feng 2024

q2 · i? · causal · r3

Cost-effectiveness analysis computed from the ingredients-method cost estimate and the RCT's effect size of 0.10 (Hedges's g), using the CER formula printed in the report; prices in 2021 dollars.

"this yields an approximate cost of $462.30 per student per standard deviation difference in performance on the long-term EOG math assessment above comparison peers."
