Summary

Low-priced Format: The Preliminary Edition is paperback, and the price is a fraction of the cost of a typical new textbook for the engineering statistics course. Simple, easy-to-read format: The Preliminary Edition is in a clean manuscript style. The first edition will have professionally designed two-color pages, and illustrations. The Preliminary Edition includes instructions for the three most popular software tools (Minitab, JMP, and Microsoft Excel). Software Integration: MINITAB, Microsoft Excel, and JMP. The text incorporates the three most popular software tools -- MINITAB and Microsoft Excel throughout, and JMP at the end of each chapter. This step-by-step approach to the use of software means no prior knowledge of their use is required. After completing a course using this text, students will be able to use these software packages to analyze statistical data in their field of interest. Breadth of coverage: Besides many popular statistical techniques, the text includes discussion of certain aspects of sampling distributions, nonparametric tests, Phase II control charts, reliability theory, design of experiments, and response surface Methodology. Phase II control charts are discussed in a separate chapter that includes the use of the statistical packages to implement these charts. Design of experiments and response surface methodology are treated in sufficient breadth and depth to be appropriate for a two-course sequence in engineering statistics that includes probability and design of experiments. Real data in examples and homework problems illustrate the importance of statistics and probability as a tool for engineers and scientists in their professional lives. All the data sets with 20 or more data points are available on the website in three formats: MINITAB, Microsoft Excel and JMP. Case studies in each chapter further illustrate the importance of statistical techniques in professional practice.
