    Introduction to Business Statistics-Statistics


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.


NEW—Integrates computer output throughout:

  • In selected examples and in exercise sets — to give students practice in interpretation with the output of statistical software packages such as SPSS, Minitab, SAS and the spreadsheet package, EXCEL.
NEW—Chapter 1 — emphasizes the science of statistics and its role in business decisions. Includes revised/expanded/new sections on:
  • Process and quality control.
  • Data collection from published sources, designed experiments, surveys, and observations.
  • Statistical thinking.
NEW—Chapter 2 — expands coverage of descriptive analytical tools that are useful in examining assumptions about data. Includes revised/expanded/new sections on:
  • Both graphical and numerical methods for summarizing qualitative data.
  • Time series plots and the graphing of bivariate data relationships (optional).
  • Variability.
NEW—Chapter 7 — provides more emphasis on confidence interval estimation procedures and their interpretation.
  • The approach to small-sample confidence intervals is motivated by pharmaceutical testing requirements.
  • Adds new optional sections on the finite population correction and survey designs.
NEW—Chapter 8 — features more balanced treatment of p-values and critical values in interpreting testing results.
  • New examples make greater use of computer solutions rather than formulas.
NEW—Chapter 9 — reorganized to present inference in the context of the experimental design used for data collection.
NEW—Chapter 10 — includes expanded coverage of correlation — which continues the emphasis, from Ch. 2, on bivariate linear relationships.
  • Where appropriate, shifts the emphasis from formulas to the interpretation of computer output, including Excel spreadsheets.
NEW—Chapter 11 — incorporates more extensive computer output and inferences about the beta parameters and includes new material on confidence intervals.
NEW—Chapter 12 — offers new/revised coverage of model-building:
  • The consequences of choosing the wrong model — i.e., the errors in prediction.
  • Models with more than two quantitative variables.
NEW—Chapter 15 — contains a separate section on multiple comparisons — with emphasis on computer output rather than formulas.
  • Presents examples of both Bonferroni's and Tukey's method.
NEW—Features Statistics in Action boxes — two or three per chapter — that examine high profile, contemporary, controversial business, economic, government, or entertainment issues that involve statistics.
  • Focus questions prompt students to form their own conclusions and to think through the statistical issues involved.
NEW—Features six extensive business problem-solving casesShow Cases — with real data and assignments.
NEW—Contains six Internet Labs designed to help students retrieve and download raw data from the internet for analysis.
NEW—Contains 60% new or revised examples and exercises — featuring real business data from 1990 to 1996.
NEW—Adds a Chapter-end Review to each chapter:
  • Quick Review — provides a list of key terms and formulas with page number references.
  • Language Lab — helps students learn the language of statistics through pronunciation guides, descriptions of symbols, names, etc.
  • Supplementary Exercises — review all of the important topics covered in the chapter.
Offers a choice in level of coverage of probability.
  • Unlike other introductory texts which mix probability and counting rules, this text includes the counting rules in a separate and optional section at the end of the chapter on probability.
  • All exercises that require the use of counting rules are marked with an asterisk.
Features extensive coverage of regression analysis — with three chapters covering simple regression, multiple regression, and model building.
  • Content is understandable, usable, and much more comprehensive than the presentations in other introductory statistics texts.
  • Discusses the major types of inferences that can be derived from a regression analysis — showing how these results appear in computer printouts and selecting multiple regression models to be used in an analysis.
Provides an abundance of exercises (1400) labeled by type and illustrating applications in almost all areas of research. All exercise sections are divided into two parts:
  • Learning the Mechanics — straightforward applications of new concepts — to test students' ability to comprehend a concept or a definition.
  • Applying the Concepts — based on applications and real data taken from a wide variety of journals, newspapers, magazines, and other sources published since 1990. These exercises develop students' skills at comprehending real world problems that describe situations to which the techniques may be applied.
Highlights important information in colored boxes — Definitions, Strategies, Key Formulas and other important information.
Provides “We're We've Been . . . We're Going” chapter openers — with quick reviews of how information learned previously applies to the chapter at hand and how the chapter topics fit into students' growing understanding of statistical inference.
Includes Footnotes that allow additional flexibility in the mathematical and theoretical level at which the material is presented. They:
  • Explain the role of calculus in various derivations.
  • Cover some of the theory underlying certain results.
