Power calculation: Minimum Detectable Effect Size for Main Outcomes
|
Before
Based on this sample size and the projected division of households across treatment arms, the study will have 80% power to detect impacts of the live call on Medicaid coverage within 6 months as small as 1.1 percentage points, impacts of the pre-recorded call as small as 0.9 percentage points, and differences between the live and pre-recorded calls as small as 1.0 percentage points.
