intuitive understanding of principles rather than learning by mathematical proof. Places greater emphasis on computer applications, providing MINITAB commands for most of the statistical techniques covered. Focusing on inferential concepts and data analysis, it presents realistic examples from nursing, physical therapy, epidemiology, public health administration, medicine and other health fields. Covers probability distributions, estimation, hypothesis testing, analysis of variance, simple linear regression and correlation, distribution-free statistics, among other topics. Some of the specific improvements to this edition include discussion of stem-and-leaf displays and box-and-whisker plots in the introduction to data analysis techniques, discussion of the trimmed mean in the section on measures of central tendency, expanded discussion of the chi-square statistic, expanded treatment of nonparametric statistics, several new end-of-section and end-of-chapter exercises and review questions.
