The textbook is for undergraduate students making their first foray into nonparametric methods, either in a mainstream statistics course or in service courses for students majoring in other disciplines. It can also be used for self-study or as a reference by professionals in various fields who understand basic statistics but have little acquaintance with nonparametric methods. Like previous revisions since 1989, this edition reflects current levels of computing power and the scope of applying nonparametric or distribution-free methods, especially the tendency to combine them with other methods.
