Chapter 7: Empirical Analysis
This chapter calculates MSE and MDE values for the posttest-only, DID, ANCOVA, and UANCOVA estimators using simulations that are based on key parameter values that are found in the literature. The focus is on RCTs for education interventions that aim to improve achievement test scores of elementary school and preschool students in low-performing school districts.
