Summary: Interesting & valuable, though philosophical > statistical
Review: I expected the author to talk much about statistical analysis and related "technical stuff". I had been very wrong. In fact, the book can be regarded as a warning to common people about the "irrelevancy" and "inaccuracy" of data or information we encounter or process so that we can perform better analysis of on our own. As from pg 197, "of primary importance from this book are the following lessons:-"
- Don't be intimidated by anyone (esp those know-it-alls)
- Be a critical thinker
- Don't confuse what's countable with what really counts
- Get organized
- Question authority
- Dig into the numbers
- Focus on the essential
- Document, document, document
- Use the internet
- Remember that others don't care as much about your work as you do
- Synthesis follows analysis
In short, a good read. Dont miss it.
p.s. I like the following quotes from the book very much. (The author did use over 31 quotes with at least one for each chapter)
Just because I use a study to refute another study does not mean my study is right. It just means I believe it. Caveat Emptor. - Cynthia Crossen
Whether or not someone else knows it all isn't really relevant; the only thing that's relevant is what you know and what you do. - Robert Ringer

Summary: Among the most influential books I've read
Review: I was expecting a book about quantitative methods and advanced problem solving techniques. What I got, instead, was a book that didn't even discuss numbers until page 111 of a 221 page book, and it was lite on problem solving techniques. Although it was not what I expected it turned out to be one of those rare books that deeply influences and provides fresh perspectives. The book led me on a journey that broke the process of critical thinking into manageable steps. Among the things I learned were:* Examine key factors, such as information, attention and action within the context of a cycle of actions that begins with goals, and moves through execution, how events in the external world influence the meeting of those goals, an evaluation and refinement of goals. Then the process starts anew. * Structured methods for getting organized. The techniques given are simple, yet powerful.How to collect and critically analyze data and information, common fallacies and how to spot them. Two of my favorite parts that reinforce these are then single-page chart titled "What Scientists Say, and What They Mean", and Chapter 20 (Uncertainty Principle and the Mass Media). * The straightforward process of numerical analysis, using relatively simple math techniques to make sense of numbers and turn them into knowledge, is priceless. What makes this part of the book valuable is that the author integrates the preceding chapters that lead you to a critical thinking mindset with common sense and techniques that are within the grasp of high school students. It looks easy, but is testimony to the author's exceptional ability to communicate and inspire. Overall this book is one of my personal favorites and one that I recommend to colleagues. Another book that complements this one nicely is Systems Thinking: Managing Chaos and Complexity by Jamshid Gharajedaghi.

Summary: Zen and the Art of Statistical Analysis
Review: In his role as leader of the End-Use Forecasting Group in the Environmental Energy Technologies Division of Lawrence Berkeley National Laboratory, Jonathan Koomey is professionally concerned with using numbers from many different sources to gain knowledge about where markets for energy-efficient technologies may be headed. It's an approach called quantitative problem solving. "Although the technical aspects of this process are taught at many universities, the art of problem solving is rarely discussed and even more rarely written down," Koomey notes in the preface. His goal is to amend that lack, helping the reader "to become a first-rate analyst in your chosen field." "Your chosen field" covers a lot of ground, and while the book delivers on Koomey's promise, much of the pleasure of reading it comes from his eccentric definition of both his topic and his audience. Not a textbook -- or not just a textbook -- "Turning Numbers into Knowledge" is aimed at students and professors alike; at problem solvers in business, government, and research; at middle managers and potential investors; and even at journalists. Beginning with a chapter titled "Beginner's Mind" and including others titled "Question Authority" and "Reflect," one might think Koomey's book could have been named "Zen and the Art of Statistical Analysis." But it's also full of technical advice, in chapters like "Let Tables and Graphs Do the Work," "Use the Internet," and many more. In fact Koomey has organized his topics thoughtfully, beginning with considerations of why anyone, professional or amateur, would undertake quantitative analysis. Koomey's bottom-line answer is that it helps us manage a runaway information explosion, which otherwise can lead to paralysis through overload or the opposite, a refusal to learn anything new. He then moves on to the mental preparation needed for problem solving, consideration of common pitfalls, critical thinking, and finally to nitty-gritty techniques. In the first chapter, "Beginner's Mind," Koomey reminds the reader that "experience is a two-edged sword. It eliminates unnecessary detail," but it can also "lead you astray when a new problem is sufficiently outside your experience." What's needed, he says, is a combination of curiosity -- the nonjudgmental observation of the beginner -- with the experience of a senior analyst. He makes his point with Bruce Lee's amusing parable of the Zen master and the Western university professor who came to inquire about Zen but never stopped talking about what he already knew. During a pause in the monologue, the master suggested tea. He poured his visitor's cup full and kept on pouring and pouring until finally the professor protested: "No more will go in!" Noting that professor's mind was like his tea cup, the master asked "How can I show you Zen unless you empty your cup?" Later, in the chapter "Question Authority," Koomey allows that sometimes following authority is essential -- in military maneuvers, for example -- but that most life situations aren't like that. Appeals to anonymous authority are immediately suspect; so are expert pronouncements by experts in an unrelated field, or those with a vested interest in the outcome. Koomey cites the "expert" testimony of researchers funded by tobacco companies who found no evidence that smoking had adverse health effects. He warns that while information on the internet is particularly susceptible to a lack of institutional validity, "any source can propagate nonsense." In an exercise from a subsequent chapter, "How guesses become facts," Koomey suggests that the reader "Find an official statistic that sounds plausible and explore its origins. Do you still find it plausible after you've investigated?" It's an exercise Koomey himself has undertaken more than once, notably with the 1998 claim that the internet was consuming eight percent of total U.S. electricity production and was well on its way to consuming half. Koomey discovered that the numbers were based on bad measurements, bad assumptions, and outright guesses -- none of which prevented them from becoming enshrined as fact before Koomey's team did their best to set things straight. In summing up, Koomey lists a dozen lessons to remember, among them "Don't be intimidated," "Get organized," "Document, document, document," and "Remember that others don't care as much about your work as you do" -- an invitation to know and persuade one's audience. It's sound advice, cheerfully and colorfully delivered by a man who knows what he's talking about, and of value to all sorts of readers -- whether or not they intend to ever crunch a single number.

Summary: Tools, tricks, & tips for solving problems in the real world
Review: Jonathan Koomey is a Staff Scientist at the Lawrence Berkeley National Laboratory, a position he has held since 1984. He got tired of explaining again and again what he describes as the "tricks of the trade" for using data and numbers to the analysts he would hire. Out of this frustration arose Turning Numbers Into Knowledge: Mastering The Art Of Problem Solving, which teaches the reader the neglected art of critical thinking. More than a mere proficiency with basic calculations, the mastery of analyzing numerically-based data requires an understanding of how people use information, the importance of ideology, the art of storytelling, and acknowledging the distinctions between facts and values. Turning Numbers Into Knowledge is the first comprehensive guide available to the general public on these and other related and essential skills. Here is a compendium of tools, tricks, and tips for solving problems in the real world, an essential ability for making independent judgements about the assertions of others by generating cogent and compelling analyses of one's own. Very highly recommended.

Summary: Read this book!
Review: This book belongs on the bookshelf of any serious analyst (not the Freudian kind, but the numerical kind!) Koomey has distilled years of experience into digestible guiding principles that will benefit the beginner and expert alike. It is rife with sensible recommendations that any in-the-trenches analyst will be able to put into practice on a daily basis. Koomey's book played a fundamental role in the development of my own analytical thinking and continues to be a vital source of guidance. If you want to improve your critical thinking skills, read this book!

Summary: not for the technically minded
Review: This is an entertaining and well written book on some of the do's and don'ts of data analysis. To quote from Dr. Beers review below, "The main emphasis is on the art of data interpretation." Indeed there are useful tools here for performing sanity checks and for asking critical questions about all sorts of data collections. ... The examples are, at best, sketchy and few in number. The anectodes are amusing but not terribly informative. I would have much preferred more concrete examples and further discussion on some technical matters. ....

Summary: It's Invaluable and Fun!
Review: Turning Numbers Into Knowledge deals with the fundamentals of analysis, research, and problem solving, not with their fashionable technical adornments. It is a tremendous resource for anyone wanting to critically review anything from costly, technical studies to everyday rhetorical argument. The adjectives that came to my mind as I read Turning Numbers Into Knowledge were, "Engaging, comprehensive, down-to-Earth, well-researched, well-written, well-planned, well-documented, creative, helpful, entertaining, filled with useful resource material, user-friendly, personal, witty, and wise." Whereas I had anticipated a ponderous technical tract, Turning Numbers Into Knowledge entertainingly deals with problem solving and analysis in its broadest context, including the often-ignored yet critical human elements. Because of its breadth, I can scarcely think of any scientist, social scientist, student, researcher, writer, or policy analyst who could not benefit from this book. Its lessons are brought home with cleverly chosen anecdotes and lucid examples. The reader is rewarded frequently with wonderful quotations and great cartoons. What Koomey says about use of the Internet, web sites, and information dissemination over the Internet also has valuable implications for modern administrators, project managers, and executive directors whose organizational management responsibilities increasingly include management and dissemination of information. As with other classics, I expect Turning Numbers Into Knowledge to be in print for a long time and would not be surprised to see students a generation from now relying on a future edition. Jon Koomey is a hard worker, clear thinker, and has produced an extraordinarily useful book that will help the practitioners of science, research, policy analysis, and journalism in the pursuit of truth.
