Nonparametric Statistical Techniques
Trent D. Buskirk, Lisa M. Willoughby, Terry T. Tomazic · Oxford University Press eBooks · 2013
The use of parametric or nonparametric approaches when analyzing data is a major decision that investigators often confront. Although this decision may impact the validity of the conclusions that investigators might draw, the decision to use nonparametric approaches is often overlooked as a viable option for a variety of reasons. The intent of this chapter is to help guide researchers on the application of both classical and modern, computationally intensive, nonparametric techniques for investigating hypotheses of interest. Demonstrations are offered using nonparametric and parametric techniques to highlight the differences in how statistical estimates and inferential results may differ between these methodologies.
