## About

### Overview

Designed for the one-term MBA or undergraduate introduction to business statistics course, this text places emphasis on data and the common techniques and methods used to analyze them in business. It introduces concepts using practical examples and illustrates them with computer output from MINITAB, Excel, and JMP. The book integrates a business decision-making case into each chapter for motivational and illustration purposes and includes a business case assignment at the end of each chapter. These cases revolve around realistic business settings with realistic data sets that put students in the role of managers who need to make business decisions based on data. Review problems requiring students to use previously learned concepts also appear throughout to promote understanding of the relationships among statistical methods.

## Efficacy and Outcomes

### Reviews

"This book is excellent overall in terms of topics covered, clarity and organization, reasonable brevity (necessary for shorter courses), great examples of statistical output from a many different types of statistical software, and the degree to which it illustrates a wide range of business applications. It also serves as a great reference for students after the introductory course is over. I think it superior to its competitors on these dimensions."

— Bruce Cooil, Vanderbilt University

"What do you view to be the three key strengths of the text? Clear and lucid explanation of key concepts. Brevity and conciseness of treatment – a systematic and structured approach to explaining the concepts well, and thereby not testing student patience! The overall organization of the text in terms of the Definition Boxes, Example Boxes, Summary of key concepts at the start of each chapter, and overall flow of topics."

— Soumen Ghosh, Georgia Tech

"What do you view to be the three key strengths of the text? Its inclusion of a fair number of modeling problems, its math level (more mature than college algebra), and its coverage of regression."

— Jerrold May, University of Pittsburgh
