Salient Features

Each chapter opens with a motivating business example that frames a question and motivates the contents of the chapter. The authors return to the example throughout the chapter, as the statistical methods are presented and provides answers to the question posed in the opening example. 4-M Analytics Examples (Motivation, Method, Mechanics, Message) provide a consistent methodology used for worked-out examples. This approach gives students a consistent structure for solving problems and presenting their findings in the appropriate context. Each chapter includes software hints on using Excel, Minitab, and JMP for calculations and to generate graphs. These hints give students a jumping off point for getting started doing statistical analysis with software. Statistics in Action case studies follow each of the four parts of the book. Each case provides an in-depth look at a business application of statistics, uses real data, and takes students through the details of using that data to address a business question.
