Welcome to Elementary Statistics: Picturing the World, Second Edition. We are grateful for the overwhelming acceptance and support of the First Edition. It is gratifying to know that our vision of combining theory, pedagogy, and design to exemplify how statistics is used to picture and describe the world has helped students learn about statistics and make informed decisions. This message—picturing the world—begins with the cover and is carefully integrated into every feature of the text. New to the Second Edition Two features in the Second Edition help students apply statistics to real-life situations and practice making decision about statistics. Uses and Abuses. Each chapter now has a full page summarizing the uses of concepts in the chapter, as well as a description of common misuses. Each "abuse" is accompanied by one or more exercises. Real Statistics—Real Decisions—Putting It All Together. Following the Review Exercises in each chapter, we have added a full-page real-life situation accompanied by exercises that ask students to use the concepts in the chapter to make decisions. The exercise sets in the Second Edition include approximately 200 new exercises, giving the students more practice in performing calculations, making decisions, providing explanations, and applying results to a real-life setting. In response to suggestions from statistics instructors, the coverage of topics in Chapters 2, 5, 7, and 9 is revised in the Second Edition. In Chapter 2, the z-score is now introduced in Section 2.5, Measures of Position. In Chapter 5, we added two new sections—Section 5.3, Normal Distributions: Finding Probabilities, and Section 5.4, Normal Distributions: Finding Values. These sections replace Section 5.3, Applications of Normal Distributions in the First Edition. Changing these sections allows the instructor to cover applications of normal distributions in greater detail and from two perspectives. In Chapter 7, section 7.1, Introduction to Hypothesis Testing, we now introduce the concept of hypothesis testing using probability values, or P-values. The concept of using rejection regions is now introduced in Section 7.2, Hypothesis Testing for the Mean (Large Samples). In Chapter 9, for instructors who prefer to cover Section 9.1, Correlation, immediately after covering graphing paired data in Chapter 2, we added a method for testing a population correlation coefficient that does not involve hypothesis testing. The method is simple and can easily be covered after Chapters 1 and 2. General Features Versatile Course Coverage. The table of contents of the text was developed to give instructors many options. For instance, by assigning the Extending the Basics exercises and spending time on the chapter projects, there is sufficient content to use the text in a two-semester course. More commonly, we expect the text to be used in a three-credit semester course or a four-semester course that includes a lab component. In such cases, instructors will have to pare down the text's 46 sections. If you want more information on sample syllabi, check the Web site that accompanies the text, www.prenhall.com/larson. Choice of Tables. Our experience has shown that students find a cumulative density function (CDF) table easier to use than a "0-to-z" table. Using the CDF table to find the area under a normal curve is the topic of Section 5.2 on pages 214-218. Because we realize that many teachers prefer to use the "0-to-z" table, we have provided an alternative presentation of Section 5.2 using the "0-to-z" table in Appendix A of the book. Graphical Approach. As with most introductory statistics texts, we begin the descriptive statistics chapter with a survey of different ways to display data graphically. A difference between this text and many others is that we continue to incorporate the graphical display of data throughout the text. For example, see the use of stem-and-leaf plots to display data on pages 348 and 349. In all, the text has over 900 graphs—surpassing all other introductory statistics texts. Variety of Real-Life Applications. We have chosen real-life applications that are representative of the majors of the students taking introductory statistics courses. These include business, psychology, health sciences, sports, computer science, political science, and many others. Choosing meaningful applications for such a diverse audience is difficult. We wanted the applications to be authentic—but they also need to be accessible. Data and Source Lines. The data sets in the book were chosen for interest, variety, and their ability to illustrate concepts. Most of the over 200 data sets contain actual data with source lines. The remaining data sets contain simulated data that, though not actual, are representative of real-life situations. All data sets containing 20 or more entries are available in a variety of electronic forms, including disk and Internet. In the exercise sets, the data sets that are available electronically are indicated by an icon. Accuracy. Every effort was made to ensure the mathematical accuracy of the examples and exercise solutions. The examples and exercises were solved by two people independently. A third person compared the independent solutions and resolved differences. If you encounter errors that we missed, please contact us so that we can correct the problem in a subsequent printing. Balanced Approach. The text strikes a balance between computation, decision making, and conceptual understanding. We have provided many Examples, Exercises, and Try It problems that go beyond mere computation. For instance, look at Exercises 31 and 32 on page 45. Students are not just asked to construct a relative frequency histogram for the given data, they are asked to go a step further and use the histogram to make a decision. Prerequisites. Statistics contains many formulas and variables, including radicals, summation notation, Greek letters, and subscripts. So, some familiarity with algebra and evaluation of algebraic expressions is a prerequisite. Nevertheless, we have made every effort to keep algebraic manipulations to a minimum—often we display informal versions of formulas using words in place of or in addition to variables. For instance, see the definitions of midpoint and relative frequency on page 34. Flexible Technology. Although most formulas in the book are illustrated with tabular "hand" calculations, we assume that most students who take this course have access to some form of technology tool, such as MINITAB, Excel, the TI-83, or SPSS. Because the use of technology varies widely, we have made the text flexible. It can be used in courses with no more technology than a scientific calculator—or it can be used in courses that require frequent use of sophisticated technology tools. For those who want specific instructions on particular technology tools, separate technology manuals are available to augment the text. Whatever your use of technology, we are sure that you agree with us that the goal of this course is not computation. Rather, it is to gain an understanding of the basic concepts and uses of statistics. Page Layout. We believe that statistics is more accessible to students when it is carefully formatted on each page with a consistent open layout. This text is the first college-level statistics book to be written to design, which means that its features (Examples, Try It problems, Definitions, or Guidelines) are not split from one page to the next. Although this process requires extra planning and work in the development stage, the result is a presentation that is clean and clear. MAA, AMATYC, NCTM Standards. This text answers the call for a student-friendly text that emphasizes the uses of statistics and not just the computation of its myriad of formulas. Our experience indicates that our job as instructors of an introductory course in statistics is not to produce statisticians but to produce informed consumers of statistical reports. For this reason, we have included many exercises that require students to provide written explanations, find patterns, and make decisions. Chapter Openers. Where You're Going—The second page of the chapter opener has a feature called Where You're Going. It gives students an overview of the chapter, exploring concepts in the context of real-world settings. Chapter Openers. Where You've Been—Each chapter begins with a two-page photographic t description of a real-life problem. The first page has a feature called Where You've Been. It shows students how the chapter fits into the bigger picture of statistics, by connecting it to topics learned in earlier chapters. Titled Examples. Every concept in the text is clearly illustrated with one or more step-by-step examples. Each of the more than 200 examples is numbered and titled for easy reference. In presenting the examples, we used an open format with a step-by-step display that students can use as a model when solving the exercises. Try Its. Each example in the text is followed by a similar problem called Try It Yourself. The answers to these problems are given in the back of the book, and the worked-out solutions are given in the Student's Solutions Manual. Section Organization. Each section is organized by learning objectives. These objectives are presented in everyday language in a margin feature called What You Should Learn. The same objectives are then used as subsection titles throughout the section. Study Tips. Most sections contain one or more study tips placed on yellow "sticky notes" in the margin. These tend to be informal learning aids, which show how to read a table, use technology, or interpret a result or a graph. Picturing the World. Each section contains a real-life "mini case study" that illustrates the important concept or concepts of the section. Each Picturing the World concludes with a question. Definitions. The critical statistics definitions are set off with gold screens. Formal definitions are often followed by guidelines that explain, in everyday English, how to apply the definition. Guidelines. Throughout the book, the presentation of a statistical formula is followed by a set of step-by-step guidelines for applying the formula. The guidelines are divided into two columns titled In Words and In Symbols. Chapter Technology Project. Each chapter has a full-page technology projects using tools from MINITAB, Excel, and TI-83, that gives students additional insight into the way technology is used to handle large data sets or complex, real-life questions. Technology Examples. Many sections contain a worked example that shows how technology can be used to calculate formulas, perform tests, or display data. Screen displays from MINITAB, Excel, and TI-83 are given. Additional screen displays are given at the ends of selected chapters, and detailed instructions are given in separate technology manuals available with the book. Insights. Most sections also contain one or more insights placed on blue "sticky notes" in the margin. The purpose of each insight is to help drive home an important interpretation or help connect different concepts. Extending the Basics. Each exercise set ends with a group of exercises called Extending the Basics. These exercises go beyond the material presented in the section (they tend to be more challenging and are not required as prerequisites of subsequent sections). Answers and Solutions. The answers to all odd-numbered exercises are given in the back of the book, and the worked-out solutions are available in the Student's Solutions Manual. Section Exercise Sets. Each section concludes with a set of exercises carefully written to nurture student understanding and proficiency. They move from basic concepts and skill development to more challenging and interpretive problems. Labeled Exercises. Most exercises are labeled for easy reference. For instance, exercises labeled Graphical Analysis ask students to use the graphs provided to answer the questions. Paired Format. Almost all exercises are given in "paired format" so that the odd-numbered exercise, whose answer is given in the back of the book, is paired with an even-numbered exercise, whose answer is not given. This paired format is commonly used in mathematics texts, but is less common in statistics texts. Chapter Summary. Each chapter concludes with a Chapter Summary that answers the questions What did you learn? This can be used as a study aid in conjunction with the Chapter Review exercises. Chapter Case Study. Each chapter has a full-page case study featuring actual data from a real-world context and a series of thought-provoking questions that are designed to illustrate the important concepts of the chapter. Real Statistics-Real Decisions. This new feature encourages students to think critically and make informed decisions about real-world data. Exercises guide students from interpretation to drawing conclusions. Statistics: Uses and Abuses. Each chapter features an expanded discussion on how statistical techniques should be used, while cautioning students about common abuses. New exercises help students to apply their knowledge. Chapter Quizzes and Cumulative Tests. Each chapter ends with a Chapter Quiz. Additionally, Cumulative Tests help students check their mastery of content from multiple chapters. The answers to all quiz and test questions are provided in the back of the book. Chapter Review Exercises. A set of Review Exercises follows each Chapter Summary. The order of the exercises follows the chapter organization. Answers to all odd-numbered exercises are given in the back of the book. Worked-out solutions are available in the Student's Solutions Manual.
