Fig. 4: Medium-term treatment effect sizes.
From: A tailored small group instruction intervention in mathematics benefits low achievers
The figure shows for grades 2 and 8 separately, the medium term effect sizes on national tests in mathematics, taken 14–18 months after the intervention, for each of the three treatments as well as the pooled treatment. Vertical error bars are 95% confidence intervals. ITT is intention-to-treat effect, LATE is local average treatment effect.
