NC TraCS Biostatistics Seminar Series: Nonparametric statistics: understanding rank-based methods & ordinal data

Investigators are often worried about normality and whether the assumptions of classical methods are met. Nonparametric tests (e.g., the Mann-Whitney U-test instead of the t-test) offer an attractive alternative. In this seminar Jeff Laux, PhD, will discuss the nature of ordinal data and rank-based analyses.

The NC TraCS Biostatistics Seminar Series helps clinical and translational researchers collaborate more effectively with consulting biostatisticians by building deeper understanding of key statistical concepts and methods. Researchers then are better able to (1) evaluate relevance of the concept or method for research aim(s) definition and choice of study design; and (2) properly interpret the results of data analysis.
