If statistics intimidate you, if you don't know a standard deviation from a standard deduction, this book uses an almost-no-math approach to helping you understand and put together business reports. It is a step-by-step guide to choosing, using, and interpreting statistics for business. Instead of teaching you arithmetic, symbols, and calculations, it teaches you how to decide what data is necessary for a report.

I like math so I bought this book to learn about statistics. There are so many errors in the first few chapters, I had to stop reading and buy a different book. From wrong figures, wrong explanations to just plain old typos. It is very confusing to read. Barnes & Noble was great, they gave me store credit for the book. Thank you.Was this review helpful?
