Single-concept exercises have been added at the beginning of each exercise set so students can be sure they have a clear understanding of important topics in every section before working comprehensive exercises. Intro Stats covers the material typically covered in an introductory statistics course, with chapters inyro multiple regression and ANOVA included on a CD for those who can go a bit further. Cover may not represent actual copy or condition available. Just Checkinganswers are at the end of the exercise sets so students can easily assess themselves.

The dynamic approach conquers the modern challenges of teaching business statistics by making it relevant, emphasizing analysis and understanding over simple computation, preparing students to be more analytical, make better business decisions, and effectively communicating results.
This text features a wealth of real data applications, with coverage of current issues, such as ethics and data mining. This text instills in readers a respect for using statistics correctly and cautiously. A focus on checking assumptions and conditions when using statistical procedures is used throughout the text and examples. Ethics in Action vignettes in every chapter illustrate the judgment needed in statistical analysis. Students learn to identify ethically challenging issues and to propose ethically and statistically sound solutions.
Questions are included for study and reflection. What Can Go Wrong? Real data is essential for demonstrating the relevance of statistics in business. Hundreds of exercises, examples, and applications are based on current events and well-known companies, engaging readers with compelling data and scenarios.
Emphasis on graphing and exploring data is evident from the first chapters on understanding data right through to the complex model-building chapters at the end. Chapter Openers present a statistical issue in a managerial setting from a well-known company. These scenarios use real data to demonstrate how statistics relates to business disciplines such as marketing, finance, and economics.
Brief Cases at the end of each chapter use real data and ask students to investigate a question or make a business decision. Students are asked to define the objective, plan the process, complete the analysis, and report their conclusion. Data for these projects are available on the included CD-ROM and the companion website, and are formatted for multiple software programs. Reports are frequently presented in the form of a business memo, helping students become familiar with framing and communicating results in a business setting.
Early introduction of regression, introduced as part of descriptive statistics, helps to set a solid foundation of this important topic, which is then built upon in later chapters. Learning aids help students study without distracting from the main message in the text.
Math Boxes show the mathematical underpinnings—proofs, derivations, and justifications—of statistical methods and concepts. These boxes are set apart from the main narrative to avoid interrupting the explanation of the topic at hand. By Hand Boxes guide students on how to compute and arrive at solutions by hand, so they can better understand how the output from technology was reached.
These optional discussions distill and explain formulas to help students through the calculation of a worked example. These questions involve little to no calculation. Answers are provided at the end of the chapter so students can check their work. What Have We Learned? The flexible topic coverage features short, modular chapters to accommodate any course objective or syllabus.
Exercises within each chapter progress in difficulty and complexity. Then, the exercises incorporate a straightforward application of the chapter ideas. Next, they tackle larger problems that ask students to work through the logic of a complete analysis. Finally, students are asked to synthesize and incorporate their own ideas. The challenging exercises would be ideal for group projects. Technology Help sections have been updated to reflect the latest technology releases.
Increased MyStatLab coverage includes more of the textbook questions, including all of the basic exercises, to give students the practice they need to gain understanding and mastery of the concepts. Basic Section Exercises have been added to ensure that students are comfortable with the requisite skills before moving on to more involved exercises.
Case Studies have been added to each part, giving students experience working through an in-depth application using real data and scenarios from actual companies. XLStat Appendix features chapter-by-chapter guidance for this new Excel add-in offered with the textbook. Some sections have been reorganized and combined for improved flow of material. Data for exercises and examples have been updated to keep the book current for students.
