An accessible text that explains fundamental concepts in business statistics that are often obscured by formulae and mathematical notation

A Guide to Business Statistics offers a practical approach to statistics that covers the fundamental concepts in business and economics. The book maintains the level of rigor of a more conventional textbook in business statistics but uses a more stream-lined and intuitive approach. In short, A Guide to Business Statistics provides clarity to the typical statistics textbook cluttered with notation and formulae.

The author--an expert in the field--offers concise and straightforward explanations to the core principles and techniques in business statistics. The concepts are intro-duced through examples, and the text is designed to be accessible to readers with a variety of backgrounds. To enhance learning, most of the mathematical formulae and notation appears in technical appendices at the end of each chapter. This important resource:

* Offers a comprehensive guide to understanding business statistics targeting business and economics students and professionals

* Introduces the concepts and techniques through concise and intuitive examples

* Focuses on understanding by moving distracting formulae and mathematical notation to appendices

* Offers intuition, insights, humor, and practical advice for students of business statistics

* Features coverage of sampling techniques, descriptive statistics, probability, sampling distributions, confidence intervals, hypothesis tests, and regression

Written for undergraduate business students, business and economics majors, teachers, and practitioners, A Guide to Business Statistics offers an accessible guide to the key concepts and fundamental principles in statistics.
