Introductory Statistics (7th Edition)

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 ofIntroductoryStatistics,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 thetermsvariableandpopulation,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 andP-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'.[read more]
