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 the world. 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 the graphing calculator, Excel, Minitab and SPSS is covered, but not required. The new Enhanced Edition includes new critical thinking and statistical literacy content, extensive technology resources including a new algorithmic test bank, new lecture slides (PowerPoint), along with a market-leading DVD series and other resources designed to provide reinforcement for students and support for instructors.
