For a one/two-term business statistics course. Designed for students with a background in basic algebra, this best- selling introduction to statistics for business and economics emphasizes inference, with extensive coverage of data collection and analysis as needed to evaluate the reported results of statistical studies and make good business decisions. It stresses the development of statistical thinking, the assessment of credibility and value of the inferences made from data-both by those who consume and those who produce them-and features numerous case studies, examples, and exercises, all drawing on real business situations and recent economic events.

Preface

This eighth edition of Statistics for Business and Economics is an introductory business text emphasizing inference, with extensive coverage of data collection and analysis as needed to evaluate the reported results of statistical studies and to make good decisions. As in earlier editions, the text stresses the development of statistical thinking, the assessment of credibility and value of the inferences made from data, both by those who consume and those who produce them. It assumes a mathematical background of basic algebra.

A briefer version of the book, A First Course in Business Statistics, is available for single semester courses that include minimal coverage of regression analysis, analysis of variance, and categorical data analysis. NEW IN THE EIGHTH EDITION Major Content Changes

Chapter 2 includes two new optional sections: methods for detecting outliers (Section 2.8) and graphing bivariate relationships (Section 2.9).

Chapter 5 now covers descriptive methods for assessing whether a data set is approximately normally distributed.

Chapter 11 is a new multiple regression chapter. The material on multiple regression models and model building (Chapters 11 and 12 in previous editions) is reorganized into a single, streamlined chapter, with initial emphasis on the first-order model. More complex models (e.g., interaction, quadratic, and dummy variable models) are presented in increasing order of difficulty. Coverage of residual analysis (Section 11.13) is expanded to include treatment of heteroscedastic errors.

Exploring Data with Statistical Computer Software and the Graphing Calculator—Throughout the text, computer printouts from four popular Windows-based statistical software packages (SAS, SPSS, MINITAB, STATISTIX) are displayed and used to make decisions about the data. New to this edition, we have included instruction boxes and output for the TI-83 graphing calculator.

Statistics in Action—One or two features per chapter examine current real-life, high-profile issues. Data from the study is presented for analysis. Questions prompt the students to form their own conclusions and to think through the statistical issues involved.

Real-World Business Cases—Six extensive business problem-solving cases, with real data and assignments. Each case serves as a good capstone and review of the material that has preceded it.

Real-Data Exercises—Almost all the exercises in the text employ the use of current real data taken from a wide variety of publications (e.g., newspapers, magazines, and journals).

Quick Review—Each chapter ends with a list of key terms and formulas, with reference to the page number where they first appear.

Language Lab—Following the Quick Review is a pronunciation guide for Greek letters and other special terms. Usage notes are also provided. TRADITIONAL STRENGTHS

We have maintained the features of Statistics for Business and Economics that we believe make it unique among business statistics texts. These features, which assist the student in achieving an overview of statistics and an understanding of its relevance in the business world and in everyday life, are as follows: The Use of Examples as a Teaching Device

Almost all new ideas are introduced and illustrated by real data-based applications and examples. We believe that students better understand definitions, generalizations, and abstractions after seeing an application. Many Exercises—Labeled by Type

The text includes more than 1,400 exercises illustrated by applications in almost all areas of research. Because many students have trouble learning the mechanics of statistical techniques when problems are couched in terms of realistic applications, all exercise sections are divided into two parts:

Learning the Mechanics. Designed as straightforward applications of new concepts, these exercises allow students to test their ability to comprehend a concept or a definition.

Applying the Concepts. Based on applications taken from a wide variety of journals, newspapers, and other sources, these exercises develop the student's skills to comprehend real-world problems and describe situations to which the techniques may be applied. A Choice in Level of Coverage of Probability (Chapter 3)

One of the most troublesome aspects of an introductory statistics course is the study of probability. Probability poses a challenge for instructors because they must decide on the level of presentation, and students find it a difficult subject to comprehend. We believe that one cause for these problems is the mixture of probability and counting rules that occurs in most introductory texts. We have included the counting rules in a separate and optional section at the end of the chapter on probability. In addition, all exercises that require the use of counting rules are marked with an asterisk (*). Thus, the instructor can control the level of coverage of probability.

Extensive Coverage of Multiple Regression Analysis

and Model Building (Chapter 11)

This topic represents one of the most useful statistical tools for the solution of applied problems. Although an entire text could be devoted to regression modeling, we believe we have presented coverage that is understandable, usable, and much more comprehensive than the presentations in other introductory statistics texts.

We devote three chapters to discussing the major types of inferences that can be derived from a regression analysis, showing how these results appear in computer printouts and, most important, selecting multiple regression models to be used in an analysis. Thus, the instructor has the choice of a one-chapter coverage of simple regression, a two-chapter treatment of simple and multiple regression, or a complete three-chapter coverage of simple regression, multiple regression, and model building. This extensive coverage of such useful statistical tools will provide added evidence to the student of the relevance of statistics to the solution of applied problems. Footnotes

Although the text is designed for students with a non-calculus background, footnotes explain the role of calculus in various derivations. Footnotes are also used to inform the student about some of the theory underlying certain results. The footnotes allow additional flexibility in the mathematical and theoretical level at which the material is presented. SUPPLEMENTS FOR THE INSTRUCTOR

The supplements for the eighth edition have been completely revised to reflect the revisions of the text. To ensure adherence to the approaches presented in the main text, each element in the package has been accuracy checked for clarity, and freedom from computational, typographical, and statistical errors.
