This book accomplishes what it sets out to accomplish admirably; it sets out the basic concepts of statistics with as little reliance on Math as possible, to give students who are not Math-oriented an idea of the subject.
If you are Math-oriented, and already know a bit about statistics, you will not learn much here. But that is not the fault of the book; it is not intended to teach someone with a grounding in the subject, any more than it is a flaw of an intro Biology textbook that it doesn't teach Organic Chemistry.
I have a couple of minor quibbles about this book, but they're really too minor to mention, and are certainly too minor to dock it a star for.
