Table of Contents
Excerpts "we live in a world of Big Data, where there is no escape from people hustling numbers. With more data, the number of possible analyses explodes exponentially. More analyses produce more smoke. The need to keep our heads clear has never been more urgent. P. 4 "My idea of big data is more expansive than the industry standard [terabytes]. The reason why we should care is is not more data, but more data analyses." P. 4. "People in industry who wax on about Big Data take it for granted that more data begets more good. Does one have to follow the other? When more people are performing more analyses more quickly , there are more theories, more points of view, more complexity, more conflicts and more confusions. There is less clarity, less consensus and less confidence." P. 11 Numbersense is difficult to teach in a traditional classroom setting. There are general principles but no cookbook. It cannot be automated. Textbook examples do not transfer to the real world. Lecture materials elevate general concepts by cutting out precisely those elements that would have burned a practioner's analysis time. The best way to nurture Numbersense is by direct practice or by learning from others." P. 14-15 Welcome to the era of Big data, and look out!" P. 15 No subjective metric can escape strategic gaming. ... The possibility of mischief is bottomless. Fighting ratings is fruitless, as they satisfy a very human need. If one scheme is beaten down, another will take its place and wear its flaws. Big Data just deepens the danger. The more complex the rating formulas, the more numerous the opportunities there are to dress up the numbers. The larger the data sets, the hard it is to audit them. Having NUMBERSENSE means: * Not taking published data at face value. * Knowing what questions to ask. * Having a nose for doctored statistics. * P. 40 Publisher Description: How to make simple sense of complex statistics--from the author of Numbers Rule Your World. We live in a world of Big Data--and it's getting bigger every day. Virtually every choice we make hinges on how someone generates data . . . and how someone else interprets it--whether we realize it or not. Where do you send your child for the best education? Big Data. Which airline should you choose to ensure a timely arrival? Big Data. Who will you vote for in the next election? Big Data. The problem is, the more data we have, the more difficult it is to interpret it. From world leaders to average citizens, everyone is prone to making critical decisions based on poor data interpretations. In Numbersense, expert statistician Kaiser Fung explains when you should accept the conclusions of the Big Data "experts"--and when you should say, "Wait . . . what?" He delves deeply into a wide range of topics, offering the answers to important questions, such as: How does the college ranking system really work? Can an obesity measure solve America's biggest healthcare crisis? Should you trust current unemployment data issued by the government? How do you improve your fantasy sports team? Should you worry about businesses that track your data? Don't take for granted statements made in the media, by our leaders, or even by your best friend. We're on information overload today, and there's a lot of bad information out there. Numbersense gives you the insight into how Big Data interpretation works--and how it too often doesn't work. You won't come away with the skills of a professional statistician. But you will have a keen understanding of the data traps even the best statisticians can fall into, and you'll trust the mental alarm that goes off in your head when something just doesn't seem to add up. Praise for Numbersense "Numbersense correctly puts the emphasis not on the size of big data, but on the analysis of it. Lots of fun stories, plenty of lessons learned—in short, a great way to acquire your own sense of numbers!" Thomas H. Davenport, coauthor of Competing on Analytics and President’s Distinguished Professor of IT and Management, Babson College "Kaiser’s accessible business book will blow your mind like no other. You’ll be smarter, and you won’t even realize it. Buy. It. Now." Avinash Kaushik, Digital Marketing Evangelist, Google, and author, Web Analytics 2.0. "Each story in Numbersense goes deep into what you have to think about before you trust the numbers. Kaiser Fung ably demonstrates that it takes skill and resourcefulness to make the numbers confess their meaning." John Sall, Executive Vice President, SAS Institute "Kaiser Fung breaks the bad news—a ton more data is no panacea—but then has got your back, revealing the pitfalls of analysis with stimulating stories from the front lines of business, politics, health care, government, and education. The remedy isn’t an advanced degree, nor is it common sense. You need Numbersense." Eric Siegel, founder, Predictive Analytics World, and author, Predictive Analytics.

Don't believe what is too rare to be true Excerpts "The present obsession with data warehouses and data-mining systems in the service of national security will surely face, as the statistical science of predicting rare events cannot provide sufficient precision to cope with the heavy costs of both false-positive and false-negative mistakes. 'Better than chance' is surely not sufficient." P. 197. "Simpson's Paradox: the simultaneous and seemingly contradictory finding that no difference exists between high-ability blacks and high-ability whites; no difference exists between low-ability whites and low-ability blacks; and when both groups are combined, blacks fare significantly worse than whites. To our amazement, the act of aggregation manufactures an apparent racial gap." P. 169 "While reading this book, it may dawn on you that numbers of all kinds rule your world. When you drive on the highway, engineers are measuring your speed at the one-and off-ramps. If your family goes to Walt Disney World, you may notice that cameras pick up your movement between rides, or you may bump into Len Testa or his crew counting heads. You now know that credit scores don't have to make sense in order to work in your favor. But when the FDA recalls this food or that, you would want to know if the agency has located those lot codes. If you or your children have taken a standardized test, you should know how the test developers choose questions that are fair to everyone. Those living in hazard-prone areas can now see why private insurers are staying away. The next time you hear a busted athlete complain about a witch hunt by steroid testers, you may wonder about those negative samples lying around in the labs. When the next lie detection program arrives to screen out potential terrorists, you may wonder about those innocent people put behind bars by mistake. After you board a plane, you will relax, knowing that you have nowhere to run. And when you decide to lay the lottery, you will look closely at the person selling you the ticket. P. 181-182. If you react in these ways, as I hope you do, you will be thinking like a statistician." p. 182. Publisher Materials WHAT ARE THE ODDS YOU'LL WIN THE LOTTERY? How long will your kids wait in line at Disney World? Who decides that “standardized tests” are fair? Why do highway engineers build slow-moving ramps? What does it mean, statistically, to be an “Average Joe”?
