Understandable Statistics is a thorough, yet approachable statistics text. Designed to help students overcome their apprehension about statistics, the text provides guidance and informal advice showing students the links between statistics and their everyday lives. To reinforce this approach, the book integrates real-life data selected from a variety of sources including journals, periodicals, newspapers and the Internet. The use of graphing calculators, Excel, Minitab and SPSS is covered, but not required. A set of technology resources accompanying the Eighth Edition, designed to provide reinforcement for struggling students, includes a market-leading video and DVD series, interactive lessons, and simulations.
