Introduction to Power Analysis for Child Welfare Program Evaluations
Why do many child welfare programs appear to have little impact? Join the Urban Institute, Portland State University, and the Evidence Building in Child Welfare project for a webinar about power analysis in child welfare program evaluations.
Some child welfare programs may be effective, but their evaluations lacked the power to detect their effectiveness. Evaluations can be underpowered by too few people participating in the program, the strength of the effects being too small, or both. Power analysis helps set up the study in a way that maximizes the ability to detect effects that actually exist. And conducting a power analysis before starting an impact evaluation is an integral part of rigorous evaluation. In this webinar, we will explain how to calculate power under various evaluation design scenarios.
