No, hang on, let's make this interesting. Between zero and infinity. Even if you stick to the whole numbers, there are a lot to choose from - an infinite number in fact. Throw in decimal fractions and infinity suddenly gets an awful lot bigger (is that even possible?) And then there are the negative numbers, the imaginary numbers, the irrational numbers like pi which never end. It literally never ends.The world of numbers is indeed strange and beautiful. Among its inhabitants are some really notable characters - pi, e, the "imaginary" number i and the famous golden ratio to name just a few. Prime numbers occupy a special status. Zero is very odd indeed: is it a number, or isn't it?How Numbers Work takes a tour of this mind-blowing but beautiful realm of numbers and the mathematical rules that connect them. Not only that, but take a crash course on the biggest unsolved problems that keep mathematicians up at night, find out about the strange and unexpected ways mathematics influences our everyday lives, and discover the incredible connection between numbers and reality itself.

    Major retailers are predicting everything from when their customers are pregnant to when they want a new pair of Chuck Taylors. It's a brave new world where seemingly meaningless data can be transformed into valuable insight to drive smart business decisions.But how does one exactly do data science? Do you have to hire one of these priests of the dark arts, the "data scientist," to extract this gold from your data? Nope.Data science is little more than using straight-forward steps to process raw data into actionable insight. And in Data Smart, author and data scientist John Foreman will show you how that's done within the familiar environment of a spreadsheet. Why a spreadsheet? It's comfortable! You get to look at the data every step of the way, building confidence as you learn the tricks of the trade. Plus, spreadsheets are a vendor-neutral place to learn data science without the hype. But don't let the Excel sheets fool you. This is a book for those serious about learning the analytic techniques, the math and the magic, behind big data.Each chapter will cover a different technique in a spreadsheet so you can follow along: - Mathematical optimization, including non-linear programming and genetic algorithms- Clustering via k-means, spherical k-means, and graph modularity- Data mining in graphs, such as outlier detection- Supervised AI through logistic regression, ensemble models, and bag-of-words models- Forecasting, seasonal adjustments, and prediction intervals through monte carlo simulation- Moving from spreadsheets into the R programming languageYou get your hands dirty as you work alongside John through each technique. But never fear, the topics are readily applicable and the author laces humor throughout. You'll even learn what a dead squirrel has to do with optimization modeling, which you no doubt are dying to know.

    As a result, the 8th edition maintains the strengths of previous editions but is enhanced with new material and current examples from public finance literature and the policy world. It includes substantive changes that reflect the progress that has been made in the field of public finance. These changes may be divided into three categories: new organization, new material, and new pedagogical features. As with previous editions, the book continues to draw upon the latest research while never losing sight of the reality it is supposed to describe, always drawing the links between economic analysis and current political issues.

    Topics covered include matrix multiplication, row reduction, matrix inverse, orthogonality and computation. The self-teaching book is loaded with examples and graphics and provides a wide array of probing problems, accompanying solutions, and a glossary.

    Old paradigms are being eclipsed by global forces of privatization and markets and new articulations of race, class, and urban space. These factors and more set the stage for Pauline Lipman's insightful analysis of the relationship between education policy and the neoliberal economic, political, and ideological processes that are reshaping cities in the United States and around the globe.Using Chicago as a case study of the interconnectedness of neoliberal urban policies on housing, economic development, race, and education, Lipman explores larger implications for equity, justice, and "the right to the city". She draws on scholarship in critical geography, urban sociology and anthropology, education policy, and critical analyses of race. Her synthesis of these lenses gives added weight to her critical appraisal and hope for the future, offering a significant contribution to current arguments about urban schooling and how we think about relations between neoliberal education reforms and the transformation of cities. By examining the cultural politics of why and how these relationships resonate with people's lived experience, Lipman pushes the analysis one step further toward a new educational and social paradigm rooted in radical political and economic democracy.

    Newman and Newman address physical, intellectual, social, and emotional growth in all life stages, focusing on the idea that development results from the interdependence of these areas at every stage, and placing special emphasis on optimal development through life. The text is noted for its clear organization, providing instructors and students with a coherent structure for tracing development over the life span. The text integrates theory and research with application, making the rich material of development useful for emerging professionals. Each life stage chapter ends with an applied topic that helps students connect the developmental themes of that stage with critical societal issues. The use of case material throughout offers a way to balance information about general patterns of development with information about individual differences and life stories. Human diversity is introduced in the very first chapter and is a continuing theme, reflected in research coverage, theoretical analysis, illustrations, and boxes. Through a variety of pedagogical strategies including the illustrations and captions, points for further reflection, and case analysis, the Newmans have created a text that encourages the reader to engage in ongoing integration and critical analysis.

    Verification that algorithms work is emphasized more than their complexity. An effective use of examples, and huge number of interesting exercises, demonstrate the topics of trees and distance, matchings and factors, connectivity and paths, graph coloring, edges and cycles, and planar graphs. For those who need to learn to make coherent arguments in the fields of mathematics and computer science.

    Appropriate for students from a wide variety of backgrounds, this comprehensive book captures women's own experiences through direct quotations and an emphasis on empirical research. Known for her balance of scholarship and readability, as well as for her inclusion of women from diverse backgrounds, Margaret Matlin continues to lead the way for the Psychology of Women course. Matlin has meticulously updated this edition to reflect the most current research, and continues to exhibit a genuine interest in and understanding of the students for whom the book is written. Her text includes a chapter on old age, and discussions of topics such as welfare issues, pregnancy and women's retirement, which are central in many women's lives, but not consistently covered in other texts.

    Politicians and marketers present shoddy evidence for dubious claims all the time. But smart people make mistakes too, and when it comes to statistics, plenty of otherwise great scientists--yes, even those published in peer-reviewed journals--are doing statistics wrong."Statistics Done Wrong" comes to the rescue with cautionary tales of all-too-common statistical fallacies. It'll help you see where and why researchers often go wrong and teach you the best practices for avoiding their mistakes.In this book, you'll learn: - Why "statistically significant" doesn't necessarily imply practical significance- Ideas behind hypothesis testing and regression analysis, and common misinterpretations of those ideas- How and how not to ask questions, design experiments, and work with data- Why many studies have too little data to detect what they're looking for-and, surprisingly, why this means published results are often overestimates- Why false positives are much more common than "significant at the 5% level" would suggestBy walking through colorful examples of statistics gone awry, the book offers approachable lessons on proper methodology, and each chapter ends with pro tips for practicing scientists and statisticians. No matter what your level of experience, "Statistics Done Wrong" will teach you how to be a better analyst, data scientist, or researcher.

    While such visualizations can better inform us, they can also deceive by displaying incomplete or inaccurate data, suggesting misleading patterns—or simply misinform us by being poorly designed, such as the confusing “eye of the storm” maps shown on TV every hurricane season.Many of us are ill equipped to interpret the visuals that politicians, journalists, advertisers, and even employers present each day, enabling bad actors to easily manipulate visuals to promote their own agendas. Public conversations are increasingly driven by numbers, and to make sense of them we must be able to decode and use visual information. By examining contemporary examples ranging from election-result infographics to global GDP maps and box-office record charts, How Charts Lie teaches us how to do just that.
