Introductory Statistics, 7e Preface Using and understanding statistics andstatistical procedures have become required skills in virtually everyprofession and academic discipline. The purpose of this book is to helpstudents grasp basic statistical concepts and techniques, and to present real-life opportunities for applying them. About This Book The text is intended for a one- or two-semestercourse and for quarter-system courses as well. Instructors can easily fit thetext to the pace and depth they prefer. Introductory high school algebra is asufficient prerequisite. Although mathematically and statistically sound, theapproach doesn't require students to examine complex concepts such asprobability theory and random variables. Students need only understand basicideas such as percentages and histograms. Advances in technology and newinsights into the practice of teaching statistics have inspired many of thepedagogical strategies used in the Seventh Edition of IntroductoryStatistics, leading to more emphasis on conceptual understanding and less emphasis oncomputation. Highlights of the Approach ASA/MAA-GuidelinesCompliant. We followASA/MAA guidelines to stress the interpretation of statistical results, thecontemporary applications of statistics, and the importance of criticalthinking. Unique Variable-Centered Approach. By consistent and proper use of theterms variable and population, we unified and clarified the various statistical concepts. Data Analysis and Exploration. We incorporate an extensive amount ofdata analysis and exploration in the text and exercises. Recognizing that notall readers have access to technology, we provide ample opportunity to analyzeand explore data without the use of a computer or statistical calculator. Detailed and Careful Explanations. We include every step of explanationthat a typical reader might need. Our guiding principle is to avoid cognitivejumps, making the learning process smooth and enjoyable. We believe thatdetailed and careful explanations result in better understanding. Emphasis on Application. Weconcentrate on the application of statistical techniques to the analysis ofdata. Although statistical theory has been kept to a minimum, we provide athorough explanation of the rationale for the use of each statisticalprocedure. Parallel Critical-Value/ P -Value Approaches. Through aparallel presentation, the book offers complete flexibility in the coverage ofthe critical-value and P -valueapproaches to hypothesis testing-either one or both approaches can be exploredand compared. ParallelPresentations of Technology. The book offers complete flexibility in the coverage of technology,which includes options for use of Minitab, Excel, and the TI-83/84 Plus. One or more technologies can beexplored and compared. New and Hallmark Features Chapter-Opening Features. Included at the beginning of eachchapter is a general description of the chapter, an explanation of how thechapter relates to the text as a whole, and an outline that lists the sectionsin the chapter. Each chapter opens with a classic or contemporary case studythat highlights the real-world relevance of the material. (Case studies arereviewed and discussed at the end of the chapter.) More than one-third of thecase studies are new or updated. Real-World Examples. Every concept discussed in the text is illustrated by at least onedetailed example. The examples are based on real-life situations and werechosen for their interest level as well as for their illustrative value. Interpretation Boxes. This feature presents the meaning and significance of statisticalresults in everyday language. Instead of just obtaining the answers or results,students are shown the importance of interpretation. What Does It Mean?. This feature, found in the margin at appropriate places, states in"plain English" the meaning of definitions, formulas, and key facts. It is alsoused to summarize various expository discussions. Data Sets. In most examples and many exercises, we present both raw data and summarystatistics. This practice gives a more realistic view of statistics andprovides an opportunity for students to solve problems by computer orstatistical calculator, if so desired. Hundreds of data sets are included, manyof which are new or updated. All data sets, including large ones, are availablein multiple formats on the WeissStats CD. Procedure Boxes: Why, When, and How. To help students learnstatistical procedures, we developed easy-to-follow, step-by-step methods forcarrying them out. Each step is highlighted and presented again within theillustrating example. This approach shows how the procedure is applied andhelps students master its steps. The procedure boxes havebeen reformatted to include the "why, when, and how" of the methods. Usually, aprocedure has a brief identifying title followed by a statement of its purpose(why it's used), the assumptions for its use (when it's used), and the stepsfor applying the procedure (how it's used). The procedures have been combinedinto a new, single split format for ease of use and comparison. The Technology Center. The in-text coverage of statistical technology includes three of themost popular applications: Minitab, Excel, and the TI-83/84 Plus graphingcalculators. We provide instructions and output for the most recent versions ofthese applications, including Release 14 of Minitab. The Technology Centers areintegrated as optional material. Computer Simulations. Computer simulations appear in both the text and theexercises. The simulations serve as pedagogical aids for understanding complexconcepts such as sampling distributions. Exercises. Over 1700 exercises provide current,real-world applications and were constructed from an extensive variety ofarticles in newspapers, magazines, statistical abstracts, journals, and Websites; sources are explicitly cited. The exercises help students learn thematerial and, moreover, show that statistics is a lively and relevant discipline.We updated exercises wherever appropriate and have provided many new ones.Exercises related to optional materials are marked with asterisks unless theentire section is optional. Most section exercise sets are divided intothree categories. Statistical Concepts and Skills exercises help students master the skills and concepts explicitly discussed inthe section. Extending the Concepts and Skills exercises invite students to extend their skills byexamining material not necessarily covered in the text. Exercises thatintroduce new concepts are highlighted in blue. Using Technology exercises provide students with an opportunity to apply and interpret thecomputing and statistical capabilities of Minitab, Excel, the TI-83/84 Plus,SPSS, or any other statistical technology. End-of-Chapter Features: Chapter Reviews. Each chapter review includes chapterobjectives , a list of Key Terms with page references, and a Review Test to help students reviewand study the chapter. Items related to optional materials are marked withasterisks unless the entire chapter is optional. Award-Winning Internet Projects. Each chapter includes an InternetProject to engage students in active and collaborative learning throughsimulations, demonstrations, and other activities, and guide them throughapplications by using Internet links to access data and other informationprovided by the vast resources of the World Wide Web. The Internet Projects are featured on the Weiss Web site atwww.aw-bc.com/weiss. Focusing on Data Analysis. A brand new database has been constructed for the Focusing on Data Analysis feature, which appears in every chapter. Students can conduct various statistical analyses on these data sets, using the technologyof their choice. This feature gives students an opportunity to work with largedata sets, to practice using technology, and to discover the many methods ofexploring and analyzing data. The Focus Database contains information on 13variables for the undergraduate students attending the University of Wisconsin- Eau Claire (UWEC). Statistical analyses can be performed for the entire population of UWEC students for topicsthat require population data. The database can be sampled to perform statistical analyses that require sampledata (e.g., inference). The database lends itself to interesting and informative class projects, asillustrated in the Chapters 8 and 9 Focusing on Data Analysis sections. The Focus Database is included on the WeissStats CD. Case Study Discussion. At the end of the chapter, thechapter-opening case study is reviewed and discussed in light of the chapter'smajor points, and then problems are presented for students to solve. StatExplore in MyMathLab. StatExplore is online statistical software available through the Weiss MyMathLab Course. At the end of each chapter of the book, we illustratethe use of StatExplore to perform a statistical analysis discussed in thechapter. For best results, students should implement the steps we present andthereby obtain the StatExplore output for themselves. Exercises encouragestudents to further apply StatExplore to other statistical analyses examined inthe chapter. Biographical Sketches. Each chapter ends with a brief biography of a famous statistician.Besides being of general interest, these biographies help students obtain aperspective on the development of the science of statistics. Procedure Index. Because of the numerous statistical procedures available, finding aspecific one is sometimes difficult. Consequently, we include a ProcedureIndex (located inside the back cover of the book), which provides a quick and easyway to find the right procedure for performing any particular statisticalanalysis. WeissStats CD. This PC and Macintosh compatible CD, included with every new copy of thebook, contains a wealth of resources. Among them are the following: Threemodular chapters that provide optional extended coverage of regressionanalysis, experimental design, and ANOVA.. Data Desk/XL (DDXL) software, an Excel add-in from Data Description, Inc., thatenhances Excel's standard statistics and graphics capabilities. Adobe Acrobat Reader software for reading the optional modular chapters. Formula/Table Card. A detachable formula/table card (FTC) is provided with the book. This cardcontains all the formulas and many of the tables that appear in the text. TheFTC is helpful for quick-reference purposes; many instructors also find itconvenient for use with examinations. Flexible Syllabus The text offers a great deal of flexibility inchoosing material to cover. The flowchart on page 000 indicateschapter-coverage flexibility. Here are some additional noteworthy items. Option for Brief Sampling Coverage. New to this edition, the onlysampling design required for study is simple random sampling, which ispresented in Section 1.3. Further sampling designs (systematic random sampling, stratifiedsampling, cluster sampling, and multistage sampling) are available in Section1.4 for coverage at the instructor's discretion. Option for Brief Experimental Design Coverage. New to this edition,coverage of experimental designs (which appears in Section 1.5) is optional.Introduction to the principles of experimental design, the terminology ofexperimental design, and basic statistical designs can be covered at theinstructor's discretion. Option for Brief Probability Coverage. Only a rudimentary coverage ofprobability is required, mostly for the frequentist interpretation ofprobability and for standard statistical terminology such as Type I and Type IIerror probabilitiesand P -values. More probability, including probability theory andrandom variables, can be covered at the discretion of the instructor. Theprobability concepts required for statistical inference can now be covered intwo or three class periods. The option for brief probability coverage iseffected by omitting sections marked as optional (with an asterisk) in Chapters4 and 5, as identified in the table of contents and in the chapter outlines forthose two chapters. Option for Early Regression Coverage. The chapter discussing descriptivemethods in regression and correlation (Chapter 14) is written so that it can becovered at any time after Chapter 3. Option for Further Regression and ANOVA. Three chapters that contain additionalmaterial on regression analysis and analysis of variance are available forcustomizing your course. These chapters, written by Professor Dennis Young ofArizona State University, are provided on the WeissStats CD, and are asfollows: Module A: Multiple Regression Analysis Module B: Model Building in Regression Module C: Design of Experiments and Analysis of Variance Organization As mentioned, the text offers a great deal of flexibility in choosing material to cover. Following is a brief chapter-by-chaptersummary. Chapter 1 presents the nature of statistics, sampling designs, and an introduction toexperimental designs. The material in Section 1.4 (Other Sampling Designs) isnow optional, as is the material on experimental designs in Section 1.5. Theoptional chapter Design of Experiments and Analysis of Variance (Module C), on theWeissStats CD, provides a more comprehensive treatment of experimental designs. Chapters 2 and 3 present the fundamentals of descriptive statistics. Quartiles aredefined intuitively and are consistent with the definition of hinges used inboxplots. Chapters 4 and 5 examine probability and discrete random variables. Only the first threesections of Chapter 4 are prerequisite to coverage of inferential statistics;the remaining five sections of Chapter 4 and all four sections of Chapter 5 areoptional. Chapter 6 provides a concise discussion of the normal distribution, including anoptional section on the normal approximation to the binomial distribution. Chapter 7 introduces the concept of sampling distributions and presents an improved andsimplified introduction to the sampling distribution of the sample mean. Chapters 8 and 9 give an easily accessible introduction to confidence intervals andhypothesis tests for one population mean by using the terminology of variablesand avoiding formal probability. Both chapters employ the -known versus -unknown criterion fordeciding which parametric procedure to use; this approach makes confidenceintervals and hypothesis tests easier to understand and apply, and provides amethod consistent with most statistical software, including Minitab, Excel(DDXL), and the TI-83/84 Plus. Chapter 9 also presents an optional section on theone-sample Wilcoxon signed-rank test. We consider Chapters 1-9 the core of anintroductory statistics course. Chapter 10 examines inferences for two population means. It contains a detaileddiscussion of the meaning of independent samples, including graphics for quickassimilation. The two-sample z -procedures are covered in the exercises so thatthe presentation can focus on the more practical two-sample t -procedures. Included inChapter 10 are separate optional sections devoted to the Mann-Whitney test andthe Wilcoxon signed-rank test for paired samples. Chapter 11, which is optional, presents material on inferences for one and twopopulation standard deviations (or variances). Chapter 12 examines inferences for one and two population proportions, and containsdiscussions of margin of error and sample-size determination. Chapter 13 introduces the chi-square goodness-of-fit test and the chi-squareindependence test. Included is a section on grouping bivariate data intocontingency tables and an easy-to-understand presentation of the concept ofassociation. Chapter14 gives an informal, but precise, treatment of regression and correlation,relying on intuitive and graphical presentation of important concepts. Theplacement is flexible-this chapter can be covered any time after Chapter 3. Chapter 15 examines inferential methods in regression and correlation. Multipleregression and model building are covered in optional chapters on both theWeissStats CD and Weiss Web site: Multiple Regression Analysis (Module A)and Model Building in Regression (Module B). These optional chaptersinclude topics such as transformations, polynomial models, qualitativepredictors, and model selection. Chapter 16 introduces analysis of variance with sections on one-way ANOVA, multiplecomparisons, and the Kruskal-Wallis test. Other types of ANOVA, includingtwo-way ANOVA and randomized block design, are discussed in the optionalchapter Design of Experiments and Analysis of Variance (Module C) on the WeissStatsCD. The following flowchart summarizes the preceding discussion and shows the interdependence amongchapters. In the flowchart, the prerequisites for a given chapter consist ofall chapters that have a path that leads to that chapter. Optional sections andchapters can be identified by consulting the table of contents. Supplements and Support FOR THE INSTRUCTOR Instructor's Edition (0-321-24138-X).
