Courses and books on basic statistics rarely cover the topic from a data science perspective. This practical guide explains how to apply various statistical methods to data science, tells you how to avoid their misuse, and gives you advice on what's important and what's not.Many data science resources incorporate statistical methods but lack a deeper statistical perspective. If you're familiar with the R programming language, and have some exposure to statistics, this quick reference bridges the gap in an accessible, readable format.With this book, you'll learn:Why exploratory data analysis is a key preliminary step in data scienceHow random sampling can reduce bias and yield a higher quality dataset, even with big dataHow the principles of experimental design yield definitive answers to questionsHow to use regression to estimate outcomes and detect anomaliesKey classification techniques for predicting which categories a record belongs toStatistical machine learning methods that "learn" from dataUnsupervised learning methods for extracting meaning from unlabeled data

    The findings will surprise many readers and, quite frankly, upset others.The ChallengeBuilt to Last, the defining management study of the nineties, showed how great companies triumph over time and how long-term sustained performance can be engineered into the DNA of an enterprise from the very beginning. But what about the company that is not born with great DNA? How can good companies, mediocre companies, even bad companies achieve enduring greatness? The StudyFor years, this question preyed on the mind of Jim Collins. Are there companies that defy gravity and convert long-term mediocrity or worse into long-term superiority? And if so, what are the universal distinguishing characteristics that cause a company to go from good to great?The StandardsUsing tough benchmarks, Collins and his research team identified a set of elite companies that made the leap to great results and sustained those results for at least fifteen years. How great? After the leap, the good-to-great companies generated cumulative stock returns that beat the general stock market by an average of seven times in fifteen years, better than twice the results delivered by a composite index of the world's greatest companies, including Coca-Cola, Intel, General Electric, and Merck. The ComparisonsThe research team contrasted the good-to-great companies with a carefully selected set of comparison companies that failed to make the leap from good to great. What was different? Why did one set of companies become truly great performers while the other set remained only good? The FindingsThe findings of the Good to Great study will surprise many readers and shed light on virtually every area of management strategy and practice. The findings include:Level 5 Leaders: The research team was shocked to discover the type of leadership required to achieve greatness.The Hedgehog Concept (Simplicity within the Three Circles): To go from good to great requires transcending the curse of competence.A Culture of Discipline: When you combine a culture of discipline with an ethic of entrepreneurship, you get the magical alchemy of great results. Technology Accelerators: Good-to-great companies think differently about the role of technology.The Flywheel and the Doom Loop: Those who launch radical change programs and wrenching restructurings will almost certainly fail to make the leap.

    But have we unwittingly handed too much away to shadowy powers behind a wall of code, all manipulated by a handful of Silicon Valley utopians, ad men, and venture capitalists? And, in light of recent data breach scandals around companies like Facebook and Cambridge Analytica, what does that mean for democracy, our delicately balanced system of government that was created long before big data, total information and artificial intelligence? In this urgent polemic, Jamie Bartlett argues that through our unquestioning embrace of big tech, the building blocks of democracy are slowly being removed. The middle class is being eroded, sovereign authority and civil society is weakened, and we citizens are losing our critical faculties, maybe even our free will.The People Vs Tech is an enthralling account of how our fragile political system is being threatened by the digital revolution. Bartlett explains that by upholding six key pillars of democracy, we can save it before it is too late. We need to become active citizens; uphold a shared democratic culture; protect free elections; promote equality; safeguard competitive and civic freedoms; and trust in a sovereign authority. This essential book shows that the stakes couldn’t be higher and that, unless we radically alter our course, democracy will join feudalism, supreme monarchies and communism as just another political experiment that quietly disappeared.

    Over years of groundbreaking experiments, he has distilled remarkable discoveries significant enough to become the bedrock of a whole new scientific field: social physics. Humans have more in common with bees than we like to admit: We’re social creatures first and foremost. Our most important habits of action—and most basic notions of common sense—are wired into us through our coordination in social groups. Social physics is about idea flow, the way human social networks spread ideas and transform those ideas into behaviors. Thanks to the millions of digital bread crumbs people leave behind via smartphones, GPS devices, and the Internet, the amount of new information we have about human activity is truly profound. Until now, sociologists have depended on limited data sets and surveys that tell us how people say they think and behave, rather than what they actually do. As a result, we’ve been stuck with the same stale social structures—classes, markets—and a focus on individual actors, data snapshots, and steady states. Pentland shows that, in fact, humans respond much more powerfully to social incentives that involve rewarding others and strengthening the ties that bind than incentives that involve only their own economic self-interest. Pentland and his teams have found that they can study patterns of information exchange in a social network without any knowledge of the actual content of the information and predict with stunning accuracy how productive and effective that network is, whether it’s a business or an entire city. We can maximize a group’s collective intelligence to improve performance and use social incentives to create new organizations and guide them through disruptive change in a way that maximizes the good. At every level of interaction, from small groups to large cities, social networks can be tuned to increase exploration and engagement, thus vastly improving idea flow.  Social Physics will change the way we think about how we learn and how our social groups work—and can be made to work better, at every level of society. Pentland leads readers to the edge of the most important revolution in the study of social behavior in a generation, an entirely new way to look at life itself.

    We live in an interesting time. Materially, everything is the best it’s ever been—we are freer, healthier and wealthier than any people in human history. Yet, somehow everything seems to be irreparably and horribly f*cked—the planet is warming, governments are failing, economies are collapsing, and everyone is perpetually offended on Twitter. At this moment in history, when we have access to technology, education and communication our ancestors couldn’t even dream of, so many of us come back to an overriding feeling of hopelessness.What’s going on? If anyone can put a name to our current malaise and help fix it, it’s Mark Manson. In 2016, Manson published The Subtle Art of Not Giving A F*ck, a book that brilliantly gave shape to the ever-present, low-level hum of anxiety that permeates modern living. He showed us that technology had made it too easy to care about the wrong things, that our culture had convinced us that the world owed us something when it didn’t—and worst of all, that our modern and maddening urge to always find happiness only served to make us unhappier. Instead, the “subtle art” of that title turned out to be a bold challenge: to choose your struggle; to narrow and focus and find the pain you want to sustain. The result was a book that became an international phenomenon, selling millions of copies worldwide while becoming the #1 bestseller in 13 different countries.Now, in Everthing Is F*cked, Manson turns his gaze from the inevitable flaws within each individual self to the endless calamities taking place in the world around us. Drawing from the pool of psychological research on these topics, as well as the timeless wisdom of philosophers such as Plato, Nietzsche, and Tom Waits, he dissects religion and politics and the uncomfortable ways they have come to resemble one another. He looks at our relationships with money, entertainment and the internet, and how too much of a good thing can psychologically eat us alive. He openly defies our definitions of faith, happiness, freedom—and even of hope itself.With his usual mix of erudition and where-the-f*ck-did-that-come-from humor, Manson takes us by the collar and challenges us to be more honest with ourselves and connected with the world in ways we probably haven’t considered before. It’s another counterintuitive romp through the pain in our hearts and the stress of our soul. One of the great modern writers has produced another book that will set the agenda for years to come.

    It could forever change how you experience and interact with your physical surroundings, open your eyes to the perversity of bad design and the desirability of good design, and raise your expectations about how things should be designed.B & W photographs and illustrations throughout.

    It’s about how people, organizations and societies can and must hit refresh—transform—in their persistent quest for new energy, new ideas, relevance and renewal. At the core, it’s about us humans and our unique qualities, like empathy, which will become ever more valuable in a world where the torrent of technology will disrupt like never before. As much a humanist as a technologist, Nadella defines his mission and that of the company he leads as empowering every person and every organization on the planet to achieve more.

    Uber and Airbnb are household names: redefining neighbourhoods, challenging the way governments regulate business and changing the way we travel.In the spirit of iconic Silicon Valley renegades like Steve Jobs and Bill Gates, a new generation of entrepreneurs is sparking yet another cultural upheaval through technology. They are among the Upstarts, idiosyncratic founders with limitless drive and an abundance of self-confidence. Young, hungry and brilliant, they are rewriting the traditional rules of business, changing our day-to-day lives and often sidestepping serious ethical and legal obstacles in the process.The Upstarts is the definitive account of a dawning age of tenacity, creativity, conflict and wealth. In Brad Stone’s highly anticipated and riveting account of the most radical companies of the new Silicon Valley, we find out how it all started, and how the world is wildly different than it was ten years ago.

     In an incredibly entertaining and inspiring narrative that draws on countless stories from their work at IDEO, the Stanford d.school, and with many of the world's top companies, David and Tom Kelley identify the principles and strategies that will allow us to tap into our creative potential in our work lives, and in our personal lives, and allow us to innovate in terms of how we approach and solve problems.  It is a book that will help each of us be more productive and successful in our lives and in our careers.

    It is damaging our health, our wealth, and our happiness and even threatening our democracy. Never has it been more pervasive or more widespread, but never has there been more that we can do about it.Even before a global pandemic introduced us to terms like "social distancing," the fabric of community was unraveling and our personal relationships were under threat. And technology isn't the sole culprit. Equally to blame are the dismantling of civic institutions, the radical reorganization of the workplace, the mass migration to cities, and decades of neoliberal policies that have placed self-interest above the collective good.This is not merely a mental health crisis. Loneliness increases our risk of heart disease, cancer, and dementia. Statistically, it's as bad for our health as smoking fifteen cigarettes a day. It's also an economic crisis, costing us billions annually. And it's a political crisis, as feelings of marginalization fuel divisiveness and extremism around the world. But it's also a crisis we have the power to solve.Combining a decade of research with firsthand reporting, Noreena Hertz takes us from a "how to read a face" class at an Ivy League university to isolated remote workers in London during lockdown, from "renting a friend" in Manhattan to nursing home residents knitting bonnets for their robot caregivers in Japan.Offering bold solutions ranging from compassionate AI to innovative models for urban living to new ways of reinvigorating our neighborhoods and reconciling our differences, The Lonely Century offers a hopeful and empowering vision for how to heal our fractured communities and restore connection in our lives.

    Rather, other factors can be even more crucial such as identifying our passions and following through on our commitments.Drawing on her own powerful story as the daughter of a scientist who frequently bemoaned her lack of smarts, Duckworth describes her winding path through teaching, business consulting, and neuroscience, which led to the hypothesis that what really drives success is not genius, but a special blend of passion and long-term perseverance. As a professor at the University of Pennsylvania, Duckworth created her own character lab and set out to test her theory.Here, she takes readers into the field to visit teachers working in some of the toughest schools, cadets struggling through their first days at West Point, and young finalists in the National Spelling Bee. She also mines fascinating insights from history and shows what can be gleaned from modern experiments in peak performance. Finally, she shares what she's learned from interviewing dozens of high achievers; from JP Morgan CEO Jamie Dimon to the cartoon editor of The New Yorker to Seattle Seahawks Coach Pete Carroll.Winningly personal, insightful, and even life-changing, Grit is a book about what goes through your head when you fall down, and how that not talent or luck makes all the difference.

    By analyzing the lives of such past masters as Charles Darwin, Benjamin Franklin, Albert Einstein, and Leonard da Vinci, as well as by interviewing nine contemporary masters, including tech guru Paul Graham and animal rights advocate Temple Grandin, Greene debunks our culture’s many myths about genius and distills the wisdom of the ages to reveal the secret to greatness. With this seminal text as a guide, readers will learn how to unlock the passion within and become masters.

    We pride ourselves on our ability to multitask--read work email, reply to a text, check Facebook, watch a video clip. Talk on the phone, send a text, drive a car. Enjoy family dinner with a glowing smartphone next to our plates. We can do it all, 24/7! Never mind the errors in the email, the near-miss on the road, and the unheard conversation at the table. In The Distracted Mind, Adam Gazzaley and Larry Rosen--a neuroscientist and a psychologist--explain why our brains aren't built for multitasking, and suggest better ways to live in a high-tech world without giving up our modern technology.The authors explain that our brains are limited in their ability to pay attention. We don't really multitask but rather switch rapidly between tasks. Distractions and interruptions, often technology-related--referred to by the authors as "interference"--collide with our goal-setting abilities. We want to finish this paper/spreadsheet/sentence, but our phone signals an incoming message and we drop everything. Even without an alert, we decide that we "must" check in on social media immediately.Gazzaley and Rosen offer practical strategies, backed by science, to fight distraction. We can change our brains with meditation, video games, and physical exercise; we can change our behavior by planning our accessibility and recognizing our anxiety about being out of touch even briefly. They don't suggest that we give up our devices, but that we use them in a more balanced way.

    Our brains, therefore, are designed not just to hunt and gather, but also to help us get ahead socially, often via deception and self-deception. But while we may be self-interested schemers, we benefit by pretending otherwise. The less we know about our own ugly motives, the better - and thus we don't like to talk or even think about the extent of our selfishness. This is "the elephant in the brain." Such an introspective taboo makes it hard for us to think clearly about our nature and the explanations for our behavior. The aim of this book, then, is to confront our hidden motives directly - to track down the darker, unexamined corners of our psyches and blast them with floodlights. Then, once everything is clearly visible, we can work to better understand ourselves: Why do we laugh? Why are artists sexy? Why do we brag about travel? Why do we prefer to speak rather than listen?Our unconscious motives drive more than just our private behavior; they also infect our venerated social institutions such as Art, School, Charity, Medicine, Politics, and Religion. In fact, these institutions are in many ways designed to accommodate our hidden motives, to serve covert agendas alongside their "official" ones. The existence of big hidden motives can upend the usual political debates, leading one to question the legitimacy of these social institutions, and of standard policies designed to favor or discourage them. You won't see yourself - or the world - the same after confronting the elephant in the brain.

    Can our world support that? What kind of world will it be? Those answering these questions generally fall into two deeply divided groups--Wizards and Prophets, as Charles Mann calls them in this balanced, authoritative, nonpolemical new book. The Prophets, he explains, follow William Vogt, a founding environmentalist who believed that in using more than our planet has to give, our prosperity will lead us to ruin. Cut back! was his mantra. Otherwise everyone will lose! The Wizards are the heirs of Norman Borlaug, whose research, in effect, wrangled the world in service to our species to produce modern high-yield crops that then saved millions from starvation. Innovate! was Borlaug's cry. Only in that way can everyone win! Mann delves into these diverging viewpoints to assess the four great challenges humanity faces--food, water, energy, climate change--grounding each in historical context and weighing the options for the future. With our civilization on the line, the author's insightful analysis is an essential addition to the urgent conversation about how our children will fare on an increasingly crowded Earth.
