This updated title in Barron’s Business Review series shows how to apply statistical methods to a variety of business situations in order to produce enlightening and profitable information. Topics covered include probability and hypothesis testing, random variables, polls and sampling, multiple linear regression, analyzing business data, decision theory, and more. Business Review books are designed for classroom use, but are also valuable as self-teaching volumes for businesspersons engaged in various fields. When used in college business courses, these titles make fine supplements to main textbooks. Instructors in adult education and brush-up programs often choose these books as their main classroom text. Each title includes review questions with answers.
Douglas Downing is Professor Emeritus of Economics at Seattle Pacific University, where he taught from 1983 to 2018. He holds a BS and a PhD in economics from Yale University. At SPU, he taught economics, quantitative methods, astronomy, and globalization. Dr. Downing also served in various leadership roles and authored 15 books, including a trilogy of math adventure novels. His 2015 book, Freedom, Opportunity, and Security, explores the relationship between economic policy and the political system.
This is a good introductory textbook for a topic that many people find quite dry - statistics. The writing is accessible and the chapters are of a length that is appropriate for properly digesting one concept before moving on to the next.
Downing and co-author Jeffrey Clark also do a nice job of providing real-world examples and business applications that help make the content seem relevant. They have a somewhat dry sense of humor that pops up from time to time as well, which make the text a touch more entertaining than your average textbook. Given that Dr. Downing is a colleague of mine at SPU, I can actually hear his "voice" and lecture delivery style as I read the text.
I confess that I read this book primarily to understand statistical concepts at a high level, but I didn't do the exercises in the book as I went along. What this means is that by the time I reached the end of the book, I had a harder time connecting with some of the models being presented. I couldn't visualize the concepts as well as I had been able to in the earlier chapters. I am sure that if I had done the work as I went, this would not have been as much of a problem.
