## Elementary Statistics 3rd Edition

This book is designed for an introductory course in statistics. The mathematical prerequisite is basic algebra. In addition to presenting the mechanics of the subject, we have endeavored to explain the concepts behind them, in a writing style as straightforward, clear, and engaging as we could make it. As practicing statisticians, we have done everything possible to ensure that the material presented is accurate and correct. We believe that this book will enable instructors to explore statistical concepts in-depth yet remain easy for students to read and understand.

To achieve this goal, we have incorporated a number of useful pedagogical features:

### Features:

• Check Your Understanding Exercises: After each concept is explained, one or more exercises are immediately provided for students to be sure they are following the material. These exercises provide students with confidence that they are ready to go on or alert them to the need to review the material just covered.
• Explain It Again: Many important concepts are reinforced with additional explanations in these marginal notes.
• Real Data: Statistics instructors universally agree that the use of real data engages students and convinces them of the usefulness of the subject. A great many of the examples and exercises use real data. Some data sets explore topics in health or social sciences, while others are based on popular cultures such as movies, contemporary music, or video games.
• Integration of Technology: Many examples contain screenshots from the TI-84 Plus calculator, MINITAB, and Excel. Each section contains detailed, step-by-step instructions, where applicable, explaining how to use these forms of technology to carry out the procedures explained in the text.
• Interpreting Technology: Many exercises present output from technology and require the student to interpret the results.
• Write About It: These exercises, found at the end of each chapter, require students to explain statistical concepts in their own words.
• Case Studies: Each chapter begins with a discussion of a real problem. At the end of the chapter, a case study demonstrates applications of chapter concepts to the problem.

### Flexibility

We have endeavored to make our book flexible enough to work effectively with a wide variety of instructor styles and preferences. We cover both the P-value and critical value approaches to hypothesis testing, so instructors can choose to cover either or both of these methods. The material on two-sample inference is divided into two chapters— Chapter 10 on two-sample confidence intervals, and Chapter 11 on two-sample hypothesis tests. This
gives instructors the option of covering all the material on confidence intervals before starting hypothesis testing, by covering Chapter 10 immediately after Chapter 8.

We have placed the material on descriptive statistics for bivariate data immediately following descriptive statistics for univariate data. Those who wish to cover bivariate description and inference together may postpone Chapter 4 until sometime before covering Chapter 13.

Instructors differ widely in their preferences regarding the depth of coverage of probability. Light treatment of the subject may be obtained by covering Section 5.1 and skipping the rest of the chapter. More depth can be obtained by covering Sections 5.2 and 5.3. Section 5.4 on counting can be included for an even more comprehensive treatment.

### Supplements

Supplements, including online homework, videos, guided student notes, and PowerPoint presentations, play an increasingly important role in the educational process. As authors, we have adopted a hands-on approach to the development of our supplements, to make sure that they are consistent with the style of the text and that they work effectively with a variety of instructor preferences. In particular, our online homework package offers instructors the flexibility to choose whether the solutions that students view are based on tables or technology, where applicable.

## New in This Edition

The third edition of the book is intended to extend the strengths of the second. Some of the changes are:
• A new objective on the weighted mean has been added.
• A large number of new exercises have been included, many of which involve real data from recent sources.
• Many new conceptual exercises have been added, for example, about detecting confounding in public health studies, drawing inferences from the shape of a histogram, interpreting technology output to detect outliers, reinforcing the concept that the Central Limit Theorem applies to the sample mean rather than individual sample items, and understanding the effect of sample size on the margin of error of a confidence interval.
• A new supplement to accompany the text has been developed that focuses on prerequisite skills.
• Several of the case studies have been updated.
• The exposition has been improved in a number of places.
