Download or read book Probably Overthinking It written by Allen B. Downey and published by University of Chicago Press. This book was released on 2023-12-06 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: An essential guide to the ways data can improve decision making. Statistics are everywhere: in news reports, at the doctor’s office, and in every sort of forecast, from the stock market to the weather. Blogger, teacher, and computer scientist Allen B. Downey knows well that people have an innate ability both to understand statistics and to be fooled by them. As he makes clear in this accessible introduction to statistical thinking, the stakes are big. Simple misunderstandings have led to incorrect medical prognoses, underestimated the likelihood of large earthquakes, hindered social justice efforts, and resulted in dubious policy decisions. There are right and wrong ways to look at numbers, and Downey will help you see which are which. Probably Overthinking It uses real data to delve into real examples with real consequences, drawing on cases from health campaigns, political movements, chess rankings, and more. He lays out common pitfalls—like the base rate fallacy, length-biased sampling, and Simpson’s paradox—and shines a light on what we learn when we interpret data correctly, and what goes wrong when we don’t. Using data visualizations instead of equations, he builds understanding from the basics to help you recognize errors, whether in your own thinking or in media reports. Even if you have never studied statistics—or if you have and forgot everything you learned—this book will offer new insight into the methods and measurements that help us understand the world.

Download or read book Bernoulli s Fallacy written by Aubrey Clayton and published by Columbia University Press. This book was released on 2021-08-03 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a logical flaw in the statistical methods used across experimental science. This fault is not a minor academic quibble: it underlies a reproducibility crisis now threatening entire disciplines. In an increasingly statistics-reliant society, this same deeply rooted error shapes decisions in medicine, law, and public policy with profound consequences. The foundation of the problem is a misunderstanding of probability and its role in making inferences from observations. Aubrey Clayton traces the history of how statistics went astray, beginning with the groundbreaking work of the seventeenth-century mathematician Jacob Bernoulli and winding through gambling, astronomy, and genetics. Clayton recounts the feuds among rival schools of statistics, exploring the surprisingly human problems that gave rise to the discipline and the all-too-human shortcomings that derailed it. He highlights how influential nineteenth- and twentieth-century figures developed a statistical methodology they claimed was purely objective in order to silence critics of their political agendas, including eugenics. Clayton provides a clear account of the mathematics and logic of probability, conveying complex concepts accessibly for readers interested in the statistical methods that frame our understanding of the world. He contends that we need to take a Bayesian approach—that is, to incorporate prior knowledge when reasoning with incomplete information—in order to resolve the crisis. Ranging across math, philosophy, and culture, Bernoulli’s Fallacy explains why something has gone wrong with how we use data—and how to fix it.

Download or read book The Creator s Game written by Allan Downey and published by UBC Press. This book was released on 2018-02-21 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: A gift from the Creator – that is where it all began. The game of lacrosse has been a central element of many Indigenous cultures for centuries, but once non-Indigenous players entered the sport, it became a site of appropriation – then reclamation – of Indigenous identities. Focusing on the history of lacrosse in Indigenous communities from the 1860s to the 1990s, The Creator’s Game explores Indigenous-non-Indigenous relations and Indigenous identity formation. While the game was being stripped of its cultural and ceremonial significance and being appropriated to construct a new identity for the nation-state of Canada, it was also being used by Indigenous peoples for multiple ends: to resist residential school experiences; initiate pan-Indigenous political mobilization; and articulate Indigenous sovereignty and nationhood on the world stage. The multilayered story of lacrosse serves as a potent illustration of how identity and nationhood are formed and reformed. Engaging and innovative, The Creator’s Game provides a unique view of Indigenous self-determination in the face of settler-colonialism.

Download or read book HT THINK LIKE A COMPUTER SCIEN written by Jeffrey Elkner and published by Samurai Media Limited. This book was released on 2016-10-04 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to teach you to think like a computer scientist. This way of thinking combines some of the best features of mathematics, engineering, and natural science. Like mathematicians, computer scientists use formal languages to denote ideas (specifically computations). Like engineers, they design things, assembling components into systems and evaluating tradeoffs among alternatives. Like scientists, they observe the behavior of complex systems, form hypotheses, and test predictions. The single most important skill for a computer scientist is problem solving. Problem solving means the ability to formulate problems, think creatively about solutions, and express a solution clearly and accurately. As it turns out, the process of learning to program is an excellent opportunity to practice problem-solving skills. That's why this chapter is called, The way of the program. On one level, you will be learning to program, a useful skill by itself. On another level, you will use programming as a means to an end. As we go along, that end will become clearer.

Download or read book Soundtracks written by Jon Acuff and published by Baker Books. This book was released on 2021-04-06 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overthinking isn't a personality trait. It's the sneakiest form of fear. It steals time, creativity, and goals. It's the most expensive, least productive thing companies invest in without even knowing it. And it's an epidemic. When New York Times bestselling author Jon Acuff changed his life by transforming his overthinking, he wondered if other people might benefit from what he discovered. He commissioned a research study to ask 10,000 people if they struggle with overthinking too, and 99.5 percent said, "Yes!" The good news is that in Soundtracks, Acuff offers a proven plan to change overthinking from a super problem into a superpower. When we don't control our thoughts, our thoughts control us. If our days are full of broken soundtracks, thoughts are our worst enemy, holding us back from the things we really want. But the solution to overthinking isn't to stop thinking. The solution is running our brains with better soundtracks. Once we learn how to choose our soundtracks, thoughts become our best friend, propelling us toward our goals. If you want to tap into the surprising power of overthinking and give your dreams more time and creativity, learn how to DJ the soundtracks that define you. If you can worry, you can wonder. If you can doubt, you can dominate. If you can spin, you can soar.
