Subclaims¶

q3 i? In a cluster randomised controlled trial, the intention-to-treat effect on disadvantaged pupils' combined InCAS reading and maths score was 0.03 with a 95% confidence interval of [-0.09, 0.14], which was not statistically significant. → Sandra McNally 2014

q3 · i? · causal · r2

Cluster randomised controlled trial with wait-list control; intention-to-treat analysis of the primary outcome (combined InCAS reading and maths, restandardised to mean 0, sd 1) for 924 disadvantaged pupils across 24 schools. Table 6a reports an effect size of 0.026 (SE 0.054, 95% CI [-0.086, 0.138]); the finding was "not statistically significant".

"The intervention showed an effect size on the disadvantaged pupils of 0.03. Similar effect sizes were found for children eligible for free school meals. This effect size is very small. However, the confidence intervals are very wide."

Discussion¶

Learner Variables¶
