This practical guide by experimentation leaders at Google, LinkedIn, and Microsoft will teach you how to accelerate innovation using trustworthy online controlled experiments, or A/B tests. Based on practical experiences at companies that each run more than 20,000 controlled experiments a year, the authors share examples, pitfalls, and advice for students and industry professionals getting started with experiments, plus deeper dives into advanced topics for practitioners who want to improve the way they make data-driven decisions. Learn how to - Use the scientific method to evaluate hypotheses using controlled experiments - Define key metrics and ideally an Overall Evaluation Criterion - Test for trustworthiness of the results and alert experimenters to violated assumptions - Build a scalable platform that lowers the marginal cost of experiments close to zero - Avoid pitfalls like carryover effects and Twyman's law - Understand how statistical issues play out in practice.

    Seasoned researchers and educators Gregory G. Colomb and Joseph M. Williams present an updated third edition of their classic handbook, whose first and second editions were written in collaboration with the late Wayne C. Booth. The Craft of Research explains how to build an argument that motivates readers to accept a claim; how to anticipate the reservations of readers and to respond to them appropriately; and how to create introductions and conclusions that answer that most demanding question, “So what?” The third edition includes an expanded discussion of the essential early stages of a research task: planning and drafting a paper. The authors have revised and fully updated their section on electronic research, emphasizing the need to distinguish between trustworthy sources (such as those found in libraries) and less reliable sources found with a quick Web search. A chapter on warrants has also been thoroughly reviewed to make this difficult subject easier for researchers Throughout, the authors have preserved the amiable tone, the reliable voice, and the sense of directness that have made this book indispensable for anyone undertaking a research project.

    For two decades, historian Alice Dreger has led a life of extraordinary engagement, combining activist service to victims of unethical medical research with defense of scientists whose work has outraged identity politics activists. With spirit and wit, Dreger offers in Galileo’s Middle Finger an unforgettable vision of the importance of rigorous truth seeking in today’s America, where both the free press and free scholarly inquiry struggle under dire economic and political threats.This illuminating chronicle begins with Dreger’s own research into the treatment of people born intersex (once called hermaphrodites). Realization of the shocking surgical and ethical abuses conducted in the name of “normalizing” intersex children’s gender identities moved Dreger to become an internationally recognized patient rights’ activist. But even as the intersex rights movement succeeded, Dreger began to realize how some fellow progressive activists were employing lies and personal attacks to silence scientists whose data revealed uncomfortable truths about humans. In researching one such case, Dreger suddenly became the target of just these kinds of attacks.Troubled, she decided to try to understand more—to travel the country to ferret out the truth behind various controversies, to obtain a global view of the nature and costs of these battles. Galileo’s Middle Finger describes Dreger’s long and harrowing journeys between the two camps for which she felt equal empathy: social justice activists determined to win and researchers determined to put hard truths before comfort. Ultimately what emerges is a lesson about the intertwining of justice and of truth—and a lesson of the importance of responsible scholars and journalists to our fragile democracy.

    How did the table fork acquire a fourth tine?  What advantage does the Phillips-head screw have over its single-grooved predecessor? Why does the paper clip look the way it does? What makes Scotch tape Scotch?   In this delightful book Henry Petroski takes a microscopic look at artifacts that most of us count on but rarely contemplate, including such icons of the everyday as pins, Post-its, and fast-food "clamshell" containers.  At the same time, he offers a convincing new theory of technological innovation as a response to the perceived failures of existing products—suggesting that irritation, and not necessity, is the mother of invention.

    But this is not the whole story.Shedding light on controversial research and investigating the ferocious gender wars in biology, psychology and anthropology, Angela Saini takes readers on an eye-opening journey to uncover how women are being rediscovered. She explores what these revelations mean for us as individuals and as a society, revealing an alternative view of science in which women are included, rather than excluded.

    In Power to the Public, Tara Dawson McGuinness and Hana Schank describe a revolutionary new approach--public interest technology--that has the potential to transform the way governments and nonprofits around the world solve problems. Through inspiring stories about successful projects ranging from a texting service for teenagers in crisis to a streamlined foster care system, the authors show how public interest technology can make the delivery of services to the public more effective and efficient.At its heart, public interest technology means putting users at the center of the policymaking process, using data and metrics in a smart way, and running small experiments and pilot programs before scaling up. And while this approach may well involve the innovative use of digital technology, technology alone is no panacea--and some of the best solutions may even be decidedly low-tech.Clear-eyed yet profoundly optimistic, Power to the Public presents a powerful blueprint for how government and nonprofits can help solve society's most serious problems.

    How can we catch schools that cheat on standardized tests? How does Netflix know which movies you’ll like? What is causing the rising incidence of autism? As best-selling author Charles Wheelan shows us in Naked Statistics, the right data and a few well-chosen statistical tools can help us answer these questions and more.For those who slept through Stats 101, this book is a lifesaver. Wheelan strips away the arcane and technical details and focuses on the underlying intuition that drives statistical analysis. He clarifies key concepts such as inference, correlation, and regression analysis, reveals how biased or careless parties can manipulate or misrepresent data, and shows us how brilliant and creative researchers are exploiting the valuable data from natural experiments to tackle thorny questions.And in Wheelan’s trademark style, there’s not a dull page in sight. You’ll encounter clever Schlitz Beer marketers leveraging basic probability, an International Sausage Festival illuminating the tenets of the central limit theorem, and a head-scratching choice from the famous game show Let’s Make a Deal—and you’ll come away with insights each time. With the wit, accessibility, and sheer fun that turned Naked Economics into a bestseller, Wheelan defies the odds yet again by bringing another essential, formerly unglamorous discipline to life.

    Kai-Fu Lee—one of the world’s most respected experts on AI and China—reveals that China has suddenly caught up to the US at an astonishingly rapid and unexpected pace.In AI Superpowers, Kai-Fu Lee argues powerfully that because of these unprecedented developments in AI, dramatic changes will be happening much sooner than many of us expected. Indeed, as the US-Sino AI competition begins to heat up, Lee urges the US and China to both accept and to embrace the great responsibilities that come with significant technological power.Most experts already say that AI will have a devastating impact on blue-collar jobs. But Lee predicts that Chinese and American AI will have a strong impact on white-collar jobs as well. Is universal basic income the solution? In Lee’s opinion, probably not.  But he provides a clear description of which jobs will be affected and how soon, which jobs can be enhanced with AI, and most importantly, how we can provide solutions to some of the most profound changes in human history that are coming soon.

    As online directories replace the yellow pages, search engines replace traditional research, and news sites replace newsprint, we are in an age in which we've come to rely tremendously on the Internet--leaving behind a trail of information about ourselves as a culture and the direction in which we are headed. With surprising and practical insight, Tancer demonstrates how the Internet is changing the way we absorb information and how understanding that change can be used to our advantage in business and in life.Click analyzes the new generation of consumerism in a way no other book has before, showing how we use the Internet, and how those trends provide a wealth of market research nearly as vast as the Internet itself. Understanding how we change is integral to our success. After all, we are what we click.

    according to an artificial intelligence trained by scientist Janelle Shane, creator of the popular blog "AI Weirdness." She creates silly AIs that learn how to name paint colors, create the best recipes, and even flirt (badly) with humans--all to understand the technology that governs so much of our daily lives.We rely on AI every day for recommendations, for translations, and to put cat ears on our selfie videos. We also trust AI with matters of life and death, on the road and in our hospitals. But how smart is AI really, and how does it solve problems, understand humans, and even drive self-driving cars?Shane delivers the answers to every AI question you've ever asked, and some you definitely haven't--like, how can a computer design the perfect sandwich? What does robot-generated Harry Potter fan-fiction look like? And is the world's best Halloween costume really "Vampire Hog Bride"?In this smart, often hilarious introduction to the most interesting science of our time, Shane shows how these programs learn, fail, and adapt--and how they reflect the best and worst of humanity. You Look Like a Thing and I Love You is the perfect book for anyone curious about what the robots in our lives are thinking.

    Founded on Jacques Bertin’s practical experience as a cartographer, Part One of this work is an unprecedented attempt to synthesize principles of graphic communication with the logic of standard rules applied to writing and topography. Part Two brings Bertin’s theory to life, presenting a close study of graphic techniques including shape, orientation, color, texture, volume, and size in an array of more than 1,000 maps and diagrams.

    Five years later, one is earning a good salary at a prestigious accounting firm. With no loans to repay, she lives in a fashionable apartment with her fiance. The other woman, saddled with burdensome debt and a low GPA, is still struggling to finish her degree in tourism. In an era of skyrocketing tuition and mounting concern over whether college is "worth it," Paying for the Party is an indispensable contribution to the dialogue assessing the state of American higher education. A powerful expose of unmet obligations and misplaced priorities, it explains in vivid detail why so many leave college with so little to show for it.Drawing on findings from a five-year interview study, Elizabeth Armstrong and Laura Hamilton bring us to the campus of "MU," a flagship Midwestern public university, where we follow a group of women drawn into a culture of status seeking and sororities. Mapping different pathways available to MU students, the authors demonstrate that the most well-resourced and seductive route is a "party pathway" anchored in the Greek system and facilitated by the administration. This pathway exerts influence over the academic and social experiences of all students, and while it benefits the affluent and well-connected, Armstrong and Hamilton make clear how it seriously disadvantages the majority. Eye-opening and provocative, Paying for the Party reveals how outcomes can differ so dramatically for those whom universities enroll.

    He argues that the only feasible explanations of scientific successes are historical explanations, and that anarchism must now replace rationalism in the theory of knowledge.

    We are increasingly coaxed from the third-dimensional containment of our pre-digital selves into a wonderful and eerie fourth dimension, a world of ceaseless communication, instant information and global connection.Our portals to this new world have been wedged open, and the silhouette of a figure is slowly taking shape. But what does it feel like to be four-dimensional? How do digital technologies influence the rhythms of our thoughts, the style and tilt of our consciousness? What new sensitivities and sensibilities are emerging with our exposure to the delights, sorrows and anxieties of a networked world? And how do we live in public, with these recoded private lives?Tackling ideas of time, space, isolation, silence and threat – how our modern-day anxieties manifest online – and moving from Hamlet to the ghosts of social media, from Seinfeld to the fall of Gaddafi, from Twitter art to Oedipus, The Four-Dimensional Human is a highly original and pioneering portrait of life in a digital landscape.

    the idea that space is not something static and neutral, a frozen entity, but is something intertwined with time and thus ever changing - also when we are not occupying it. Doreen's descriptions of her journey through England for example are clear and precise accounts of this idea, and she very sharply characterizes the attempts not to recognize this idea as utopian and nostalgic." - Olafur EliassonIn this book, Doreen Massey makes an impassioned argument for revitalising our imagination of space. She takes on some well-established assumptions from philosophy, and some familiar ways of characterising the twenty-first century world, and shows how they restrain our understanding of both the challenge and the potential of space.The way we think about space matters. It inflects our understandings of the world, our attitudes to others, our politics. It affects, for instance, the way we understand globalisation, the way we approach cities, the way we develop, and practice, a sense of place. If time is the dimension of change then space is the dimension of the social: the contemporaneous co-existence of others. That is its challenge, and one that has been persistently evaded. For Space pursues its argument through philosophical and theoretical engagement, and through telling personal and political reflection. Doreen Massey asks questions such as how best to characterise these so-called spatial times, how it is that implicit spatial assumptions inflect our politics, and how we might develop a responsibility for place beyond place.This book is "for space" in that it argues for a reinvigoration of the spatiality of our implicit cosmologies. For Space is essential reading for anyone interested in space and the spatial turn in the social sciences and humanities. Serious, and sometimes irreverent, it is a compelling manifesto: for re-imagining spaces for these times and facing up to their challenge.
