TEXT
Statistics For Business And Economics (Edition 12)
Applications of data analysis and statistical methodology are an integral part of the or- ganization and presentation of the text material. The discussion and development of each technique is presented in an application setting, with the statistical results providing insights to decisions and solutions to problems.
Although the book is applications oriented, we have taken care to provide sound method- ological development and to use notation that is generally accepted for the topic being covered. Hence, students will find that this text provides good preparation for the study of more ad- vanced statistical material. A bibliography to guide further study is included as an appendix.
The text introduces the student to the software packages of Minitab 16 and Microsoft® Office Excel 2010 and emphasizes the role of computer software in the application of statistical analysis. Minitab is illustrated as it is one of the leading statistical software packages for both education and statistical practice. Excel is not a statistical software package, but the wide avail- ability and use of Excel make it important for students to understand the statistical capabilities of this package. Minitab and Excel procedures are provided in appendixes so that instructors have the flexibility of using as much computer emphasis as desired for the course. StatTools, a commercial Excel add-in developed by Palisade Corporation, extends the range of statistical options for Excel users. We show how to download and install StatTools in an appendix to Chapter 1, and most chapters include a chapter appendix that shows the steps required to accomplish a statistical procedure using StatTools. We have made the use of Stat Tools optional so that instructors who want to teach using only the standard tools available in Excel can do so.
