概述 | What is sample attrition, why does it matter, and how does it factor into study ratings in the Home Visiting Evidence of Effectiveness (HomVEE) review? This new brief from the HomVEE team gives an overview of the issues related to attrition and how it can affect evaluation findings.", |
摘要 | A randomized controlled trial (RCT) offers a highly credible way to evaluate the effect of a program. However, a strong design can be offset by weaknesses in planning or execution. One common problem that weakens the conclusions of RCTs is attrition, or missing data. This brief describes what attrition is, why it matters, and how it factors into the study ratings in the HomVEE review. |
