Numbersense: How to Use Big Data to Your Advantage

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 "I laughed my way through this superb-useful-fun book and learned and relearned a lot. Highly recommended!" Tom Peters, author of In Search of Excellence

Surviving the Top Ten Challenges of Software Testing: A People-Oriented Approach

This is the digital version of hte printed book (Copyright © 1997). Software testers require technical and political skills to survive what can often be a lose-lose relationship with developers and managers. Whether testing is your specialty or your stepping stone to a career as a developer, there's no better way to survive the pressures put on testers than to meet the ten challenges described in this practical handbook. This book goes beyond the technical skills required for effective testing to address the political realities that can't be solved by technical knowledge alone. Communication and negotiation skills must be in every tester's tool kit. Authors Perry and Rice compile a "top ten" list of the challenges faced by testers and offer tactics for success. They combine their years of experience in developing testing processes, writing books and newsletters on testing, and teaching seminars on how to test. The challenges are addressed in light of the way testing fits into the context of software development and how testers can maximize their relationships with managers, developers, and customers. In fact, anyone who works with software testers should read this book for insight into the unique pressures put on this part of the software development process. "Somewhere between the agony of rushed deadlines and the luxury of all the time in the world has got to be a reasonable approach to testing."—from Chapter 8 The Top Ten People Challenges Facing Testers Challenge #10: Getting Trained in Testing Challenge #9: Building Relationships with Developers Challenge #8: Testing Without Tools Challenge #7: Explaining Testing to Managers Challenge #6: Communicating with Customers—And Users Challenge #5: Making Time for Testing Challenge #4: Testing What's Thrown Over the Wall Challenge #3: Hitting a Moving Target Challenge #2: Fighting a Lose-Lose Situation Challenge #1: Having to Say No

Infoglut

Today, more mediated information is available to more people than at any other time in human history. New and revitalized sense-making strategies multiply in response to the challenges of "cutting through the clutter" of competing narratives and taming the avalanche of information. Data miners, "sentiment analysts," and decision markets offer to help bodies of data "speak for themselves"—making sense of their own patterns so we don’t have to. Neuromarketers and body language experts promise to peer behind people’s words to see what their brains are really thinking and feeling. New forms of information processing promise to displace the need for expertise and even comprehension—at least for those with access to the data. Infoglut explores the connections between these wide-ranging sense-making strategies for an era of information overload and "big data," and the new forms of control they enable. Andrejevic critiques the popular embrace of deconstructive debunkery, calling into question the post-truth, post-narrative, and post-comprehension politics it underwrites, and tracing a way beyond them.

Risk Assessment and Decision Analysis with Bayesian Networks

Although many Bayesian Network (BN) applications are now in everyday use, BNs have not yet achieved mainstream penetration. Focusing on practical real-world problem solving and model building, as opposed to algorithms and theory, Risk Assessment and Decision Analysis with Bayesian Networks explains how to incorporate knowledge with data to develop and use (Bayesian) causal models of risk that provide powerful insights and better decision making. Provides all tools necessary to build and run realistic Bayesian network models Supplies extensive example models based on real risk assessment problems in a wide range of application domains provided; for example, finance, safety, systems reliability, law, and more Introduces all necessary mathematics, probability, and statistics as needed The book first establishes the basics of probability, risk, and building and using BN models, then goes into the detailed applications. The underlying BN algorithms appear in appendices rather than the main text since there is no need to understand them to build and use BN models. Keeping the body of the text free of intimidating mathematics, the book provides pragmatic advice about model building to ensure models are built efficiently. A dedicated website, www.BayesianRisk.com, contains executable versions of all of the models described, exercises and worked solutions for all chapters, PowerPoint slides, numerous other resources, and a free downloadable copy of the AgenaRisk software.

Measuring Sustainability

' Measuring the sustainability of development is crucial to achieving it, and is one of the most actively studied issues in the area. To date, most studies of measurements or indicators have been largely theoretical.

However, this book, a follow-on to Bell and Morse's highly influential Sustainability Indicators (1999), presents valuable practical advice on how to develop measurements that will work in real-life development contexts. It describes and analyses how to derive, validate and apply indicators in the course of an actual development project - in this case the Mediterranean Action Plan in Malta.

The authors explain the trade-offs and constraints involved and how it is possible to combine the open-ended and flexible perspectives of sustainability with the more linear processes and fixed targets of specific projects through the use of pragmatic and reflective methodologies.
