Essential Statistics

An introductory text for students taking a first course in statistics, Essential Statistics, Fourth Edition thoroughly updates and enhances the hugely successful third edition. It presents new information on modern statistical techniques, such as analysis of variance, and software such as Minitab. The author writes in his trademark easy-to-follow style and emphasizes the principles and assumptions underlying the statistical methods. Keeping complex mathematical theory to a minimum, he presents a wealth of fully explained, worked examples. End-of-chapter worksheets relate to a variety of fields and illustrate the relevance of the methods to a broad range of disciplines.
