• Jay L. Devore

  Jay Devore is Professor Emeritus of Statistics at California Polytechnic State University. He earned his undergraduate degree in Engineering Science from the University of California at Berkeley, spent a year at the University of Sheffield in England, and finished his Ph.D. in statistics at Stanford University. Jay previously taught at the University of Florida and at Oberlin College and has had visiting appointments at Stanford, Harvard, the University of Washington, New York University, and Columbia University. From 1998 to 2006, he served as Chair of the Cal Poly Statistics Department. In addition to this book, Jay has written several other widely used statistics texts for engineers and scientists and a book in applied mathematical statistics. He recently coauthored a text in probability and stochastic processes. He is the recipient of a distinguished teaching award from Cal Poly, is a Fellow of the American Statistical Association, and has served several terms as an Associate Editor of the “Journal of the American Statistical Association.” In his spare time, he enjoys reading, cooking and eating good food, tennis, and travel to faraway places. He is especially proud of his wife, Carol, a retired elementary school teacher, his daughter Allison, who has held several high-level positions in nonprofit organizations in Boston and New York City, and his daughter Teresa, a high school teacher in Brooklyn.

• Updated Hypothesis Testing: Hypothesis testing is now based exclusively on P-values; methodology based on rejection regions has been deleted. This better aligns the book with current statistical practice.

• Authentic Data: Multiple new examples and exercises based on real data or actual problems give students practice with statistics for the modern era.

• Practical Probability: Examples and exercises in Chapters 2 through 5 are now based on information from published sources, helping to link the concepts to contemporary issues and problems that engineers and scientists encounter in their work environment and in everyday life.

• Clearer Narratives: Polished for even better clarity, chapters focus on delivering a deep, intuitive understanding of the concepts, instead of the purely theoretical approach favored by other texts.

• Introduce students to statistical data analysis using R with the new R Companion for Probability and Statistics for Engineering and the Sciences, 9th Edition. This solution offers a supplemental eBook, homework problems and real-world examples that show students how to approach topics using R.

• NEW for Fall 2020 - Turn your students into statistical thinkers with the Statistical Analysis and Learning Tool (SALT). SALT is an easy-to-use data analysis tool created with the intro-level student in mind. It contains dynamic graphics and allows students to manipulate data sets in order to visualize statistics and gain a deeper conceptual understanding about the meaning behind data. SALT is built by Cengage, comes integrated in Cengage WebAssign Statistics courses and available to use standalone.

• Authentic Data: Multiple new examples and exercises based on real data or actual problems give you practice with statistics for the modern era.

• Practical Probability: Examples and exercises in chapters 2 through 5 are now based on information from published sources, helping to link the concepts to contemporary issues in the workplace and at actual companies.

• Clearer Narratives: Polished for even better clarity, chapters guide you toward a deep, intuitive understanding of the concepts, instead of the purely theoretical approach favored by other texts.

• Helpful Study Aids: Sample exams and a glossary of symbols and acronyms give students the experience and confidence they need to master concepts and ace exams.

• Key Focal Points: The author emphasizes the critical role that variation plays in statistics, including the nature of variation in the slope estimate in simple linear regression, and includes a detailed description of pooled t procedures for analysis.

• Sampling Simulations: "Simulation Experiments" in the text help students understand sampling distributions and the insights to gain from them, particularly when derivations are too complex to carry out.

• Computer Focus: An abundance of computer output from various statistical software packages supports student understanding of data analysis in the real world, while Java™ Applets specifically designed for this calculus-based text demonstrate statistics visually.

• Strong Connections: Chapters and exercises refer to material covered in earlier sections, making it easier for you to see connections between concepts as you move forward in your studies.

• Sampling Simulations: Simulation Experiments in the text help you grasp sampling distributions and the insights to gain from them, particularly when derivations are too complex to carry out.

• Computer Focus: An abundance of computer output from SAS® and MINITAB® supports your understanding of ANOVA and regression, while Java™ Applets specifically designed for this calculus-based text demonstrate statistics visually.

• Handy Decoding: A complete, back-of-the-book glossary of symbols and abbreviations, including text page references, serves as a convenient study aid and quick reference guide.

• Practice Exams: Designed to prepare you for the real thing, these practice exams cover a number of subjects—descriptive statistics, probability concepts, discrete probability distributions, continuous probability distributions, point estimation based on a sample, confidence intervals, and tests of hypotheses—and will boost your confidence too!
