# Overview

This worldwide best-selling business statistics text emphasizes applications over calculation. STATISTICS FOR MANAGEMENT AND ECONOMICS, 9e, demonstrates how vital statistical methods are for today's managers and economists--and teaches students how to apply these tools to real business problems. Through the author's unique three-step "ICI" approach to problem solving, students learn to IDENTIFY the correct statistical technique by focusing on the problem objective and data type, then COMPUTE the statistics (doing them by hand, using Excel®, or using MINITAB), and ultimately INTERPRET results in the context of the problem. This approach enhances student comprehension and skills while offering you maximum flexibility. Incorporating various functional areas of business, data-driven examples, exercises, and cases demonstrate statistical applications used by marketing managers, financial analysts, accountants, economists, and others, giving students the hands-on practice they need, while sound pedagogical elements make the material accessible to undergrads. In addition, unique teaching and learning resources such as CourseMate save time while giving you more control and better student outcomes. The ninth edition also includes Excel® 2010 and MINITAB 15 content.

## Features

• Emphasis on identification and interpretation provides students with practical skills they can apply to real problems they will face whether a course uses manual or computer calculations.

• Students learn that statistics is a method of converting data into information. With a substantial number of data files and corresponding problems that ask students to interpret statistical results, students are provided ample opportunities to practice data analysis and decision making.

• The optional use of the computer allows for larger and more realistic exercises and examples.

• Using Excel 2010.

# New to this edition

• Six large real datasets are the sources of 150 new exercises. Students will have the opportunity to convert real data into information. Instructors can use the datasets for hundreds of additional examples and exercises.
• Many of the examples, exercises, and cases using real data in the eighth edition have been updated. These include the data on wins, payrolls, and attendance in baseball, basketball, football, and hockey, returns on stocks listed on the New York Stock Exchange, NASDAQ, and Toronto Stock Exchange, and global warming.
• Chapter 2 in the eighth edition, which presented graphical techniques has been split into Chapters 2 and 3 for the ninth edition. Chapter 2 describes graphical techniques for nominal data and Chapter 3 presents graphical techniques for interval data. Some of the material in the eighth edition Chapter 3 has been incorporated into the new Chapter 3.
• To make room for the new additional exercises we have removed Section 12.5 Applications in Accounting: Auditing and Section 18.4 Logistic Regression. Instructors who wish to have these can download them on the CourseMate site.
• The Excel workbooks that compute confidence interval estimators and hypothesis tests have been replaced with subsections that teach students to do it on their own. This section is called "Do-It-Yourself Excel."
• There are many new examples and exercises.
