Abstract
Research in medical trauma often assesses heavily skewed, non-normal data using mean-based testing. This study explores the robustness of various tests on simulated data approximating such variables, such as Injury Severity Score (ISS) and length of stay (LOS). The appropriateness of nonparametric tests on non-normal data are discussed.
