Welcome to the Companion Website

This site is intended to enhance your use of Nonparametric Statistics for Health Care Research, Second Edition, by Marjorie A. Pett. Please note that all the materials on this site are especially geared toward maximizing your understanding of the material. 

What do you do when you realize that the data set from the study that you have just completed violates the sample size or other requirements needed to apply parametric statistics? Nonparametric Statistics for Health Care Research was developed for such scenarios—research undertaken with limited funds, often using a small sample size, with the primary objective of improving client care and obtaining better client outcomes. Covering the most commonly used nonparametric statistical techniques available in statistical packages and on open-resource statistical websites, this well-organized and accessible Second Edition helps readers, including those beyond the health sciences field, to understand when to use a particular nonparametric statistic, how to generate and interpret the resulting computer printouts, and how to present the results in table and text format.


We gratefully acknowledge Marjorie A. Pett for writing an excellent text and creating the materials on this site.
