《Basics of Statistics and Statistical Application with Excel》先讲理论，后讲统计学在excel中的应用，理论以必需够用为原则，具体应用介绍清晰、细致，实战技巧详实，理论实践结合，有利于读者掌握统计学以及excel中的相关知识。

前言

Welcome to the exciting world of statistics! We have written this book to make statistics accessible to everyone, including those with a limited mathematics background.Statistics affects all ***ects of our lives.Whethe***e are testing new medical devices of determining what will entertain us, applicati*** of statistics are so numerous that, in a sense, we are limited only by our own imagination in discovering new uses for statistics.

The edition of Basics of Statistics and Statistical Application with Excel continues to emphasize concepts of statistics.Statistical methods are carefully presented with a focus on understanding both the suitability of the method and the meaning of the result.Statistical methods and measurements are developed in the context of applicati***.

We have retained and expanded features that made the teaching materials used in Hubei University of Technology very readable.New procedure displays summarize steps for ***yzing data.Examples, exercises, and problems touch on applicati*** appropriate to a broad range of interests.Technology-based components give both students and researchers additional resources.

The book,which helps to solve practical problems, also introduces the application of statistical knowledge of Excel, and is intended for anyone reading it to learn the basics and apply Excel’s powerful statistical tools to their business courses o***ork activities.If understanding statistics isn’t your strongest suit, you are not especially mathematically-inclined, or if you are wary of computers, then this is the right book for you.

You will learn how to use key statistical tests using Excel without being overpowered by the underlying statistical theory.This book clearly and methodically shows and explains how to create and use these statistical tests to solve practical problems in business.Excel is an easily available computer program for students, instructors, and managers.It is also an effective teaching and learning tool for quantitative ***yses in business courses.The powerful nume-rical computational ability and the graphical functi*** available in Excel make learning statistics much easier than in years past.

However, this is the first book to introduce the basics of statistics and the Excel application.We hope the Excel’s capabilities will be more effective to teach business statistics; it also focuses exclusively on this topic in an effort to render the subject matter not only applicable and practical, but also easy to comprehend and apply.
