With Statistics: A Gentle Introduction, Fourth Edition , an introductory statistics class doesn't be difficult or dull. This textbook has been specifically designed to put students at ease and minimize unnecessary formulas while providing a comprehensive review of basic statistical designs and analyses. A wealth of additional real-world examples give a sense of how the science of statistics works, solves problems, and helps us make informed choices about the world we live in. The author provides a step-by-step approach to statistical tests instead of using formulas or memorizing by rote. In each chapter, a glossary of key terms, symbols, and definitions helps students understand the concepts and interpretations of statistics. Every chapter also includes a short story about historical or contemporary statisticians who helped advance statistics through unique applications. New to the Fourth Edition are advice for working with larger datasets, or big data, new coverage of some alternative non-parametric tests, discussions of p values in the context of research, an expanded discussion of confidence intervals, and more exercises for students under the new feature Test Yourself.
