In the numbers explosion all around us in our modern-day dealings, the buzzword is data, as in, “Do you have any data to support your claim?” “The data supported the original hypothesis that . . .” and “The data bear this out. . . .” But the field of statistics is not just about data. Statistics is the entire process involved in gathering evidence to answer questions about the world, in cases where that evidence happens to be numerical data.

5.0 out of 5 stars An excellent overview and/or review September 21, 2007

By L. F. Smith TOP 1000 REVIEWERVINE™ VOICE

Format:Paperback|Amazon Verified Purchase

Statistics for Dummies is an excellent overview of the fundamentals of statistics for those who have forgotten some of what they previously learned, those whose instructors left them dazed and confused, or those who just need a quick reference. Like all of the "for Dummies" books, it's not really intended to be a comprehensive instructional program or a definitive reference book. In my view, the book does exactly what it's intended to do.

Several reviewers have mentioned the lack of examples or exercises. They're right; however, there is a companion volume by the same author, Statistics Workbook for Dummies, that solves that problem. Why didn't they do it all in one book? Probably because it would have totaled over 600 pages.

So, this book won't teach you statistics from scratch, but it is a very good introductory level overview of the subject. Like all of the Dummies books, the format is attractive, the organization is clear, and the information is presented in small, easily digestible blocks. More importantly, the author uses just the right approach. She is both thorough and authoritative, but she doesn't assume much expertise among the readers. At the same time, she's never condescending.

This book is well worth the cost, and I recommend it highly.

2.0 out of 5 stars Not the college refresher I'd hoped for May 31, 2006

By T. Murphy

Format:Paperback|Amazon Verified Purchase

This book covers material that would be found in the early to mid-level phases of a college Statistics course. I was hoping for a deeper refresher, short of re-reading my college texts and notes, and this wasn't the place to find it.

Nonetheless, there are positives worth considering. This book spends a good amount of time discussing normal distributions, the errors encountered in sampling a population, and the testing of hypotheses based on sample statistics. In particular, the explanations for using a Z-distribution or t-distribution were much clearer than any I'd ever read in several university texts. In fact, the textual descriptions are among the most valuable portions of the book, in part because the quantitative portions are scarce.

On the bad side, waaay too much space is devoted to public surveys and the confidence you should or should not place in them. Those chapters could have been condensed into a single entry, and the repeated examples of misleading or incorrect statistical measures were not necessary. There's also virtually nothing on probabilities, the study of which is usually linked to statistics in the introductory courses.

There's simply not enough valuable material to make this a good choice for college prep or refresher material, and as an introductory text, you'll find better alternatives as well.

2.0 out of 5 stars Lots missing July 30, 2004

By ruatha

Format:Paperback

I agree that this is a fair OVERVIEW. But where the entire Dummies series focuses on making complex topics simple and practical, this book fall short. For instance, there is very little value in the Probabilities section; the examples used as so simplistic that they cannot be applied by the reader to any larger question. Want to know the odds of something happening with multiple independent trials? Want to really understand games of chance or card games? Want to figure out for yourself the likelihood of being called on in class over the course of a week? This book can't help you answer these questions. No formulas for individual or multiple trials, dependent or independent events, or the like are presented to enable you to use the examples that are given.

As for general statistics, again this is a fair vehicle to understand statistics in their application, not so good at explaining how they are derived or allowing the reader to apply the information.

In the end I gave this book to my college-bound daughter and she will use it as a companion guide in her stats class. It remains to be seen whether it will add any value even there.

Not a waste of money for someone wanting to understand stats in the media and the like, but certainly a disappointment if you want a refresher on how to crunch the numbers yourself.
