Taking a systematic approach to teaching statistical methods, Understandable Statistics, 6/e, is designed to help introductory-level students overcome their apprehension about statistics. The authors provide students with plenty of guidance and informal advice, in addition to showing students the links between statistics and the world around them.
Already the only semester-long statistics book to integrate graphing technology and real life data, Understandable Statistics, 6/e, now adds a wealth of new real-world features including updated exercises, collaborative projects, data, and integration of Internet use.
Note: Every chapter begins with a Chapter Overview, and includes a Summary, Important Words and Symbols, and Chapter Review Problems. Chapters 2-12 conclude with Data Highlights: Group Projects, Linking Concepts: Writing Projects, and Using Technology.
