Airbag Moderation: Power Analysis via Simulation plus Empirical Examples in Education (Poster 3)

• In Event: Innovations in Statistical Power, Intervention Planning and Design, and Causal Effects

Abstract

Presented at AERA 2018 and published in 2020, Airbag Moderation is a research hypothesis that helps researchers ask empirically-testable research questions concerning matters of educational equity. It is particularly suited for investigations of the extent to which educational inequities are related to ‘selection effects’ in education (who goes where, gets what, and how much). However, to date there has been no power analysis of the statistical methods available for testing Airbag Moderation, and few empirical examples illustrating how Airbag Moderation can advance our understanding of educational inequity. This paper provides a power analysis (via simulation) of the two most common statistical approaches to Airbag Moderation plus two empirical examples of Airbag Moderation uncovering selection effects linked to educational inequity.
