The Misuse of Normality Tests as Gatekeepers for Research in Prehospital and Disaster Medicine

This editorial discusses the common practice of using normality tests as a preliminary step for choosing between parametric and non-parametric methods. The editorial argues that such pre-testing is theoretically unfounded and practically harmful, as parametric tests are robust to moderate deviations from normality, while reliance on normality tests can distort error rates and mislead researchers.

Abstract

This editorial discusses the common practice of using normality tests as a preliminary step for choosing between parametric and non-parametric methods. The editorial argues that such pre-testing is theoretically unfounded and practically harmful, as parametric tests are robust to moderate deviations from normality, while reliance on normality tests can distort error rates and mislead researchers.
