Penguin Books Ltd The Black Swan
Book SynopsisThe phenomenal international bestseller that shows us how to stop trying to predict everything - and take advantage of uncertaintyWhat have the invention of the wheel, Pompeii, the Wall Street Crash, Harry Potter and the internet got in common? Why are all forecasters con-artists? Why should you never run for a train or read a newspaper? This book is all about Black Swans: the random events that underlie our lives, from bestsellers to world disasters. Their impact is huge; they''re impossible to predict; yet after they happen we always try to rationalize them. ''Taleb is a bouncy and even exhilarating guide ... I came to relish what he said, and even develop a sneaking affection for him as a person'' Will Self, Independent on Sunday''He leaps like some superhero of the mind'' Boyd Tonkin, IndependentTrade ReviewA fascinating study of how we are regularly taken for suckers by the unexpected * Guardian *Like the conversation of a raconteur ... hugely enjoyable - compelling * Financial Times *It has altered modern thinking * The Times *Confirms his status as a guru for every would-be Damien Hirst, George Soros and aspirant despot * Sunday Times *The Black Swan changed my view of how the world works -- Daniel Kahneman, author of Thinking, Fast and SlowGreat fun... brash, stubborn, entertaining, opinionated, curious, cajoling -- Stephen J.

Penguin Books Ltd A Field Guide to Lies and Statistics
Book SynopsisA guide to critical thinking in the ''post-truth'' era, from the author of Sunday Times best-seller The Organized Mind We live in a world of information overload. Facts and figures on absolutely everything are at our fingertips, but are too often biased, distorted, or outright lies. From unemployment figures to voting polls, IQ tests to divorce rates, we''re bombarded by seemingly plausible statistics on how people live and what they think. Daniel Levitin teaches us how to effectively ask ourselves: can we really know that? And how do they know that? In this eye-opening, accessible guide filled with fascinating examples and practical takeaways, acclaimed neuroscientist Daniel Levitin shows us how learning to understand statistics will enable you to make better, smarter judgements on the world around you.Trade ReviewIn a post-truth world, Levitin's book is an invaluable primer on how to sort the fact from the fiction * Sunday Times *The world is awash with data, but not always with accurate information.

CRC Press Dental Statistics Made Easy
Book SynopsisThis essential textbook presents the basics of dental statistics in an accessible way, combining explanation in non-technical language with key messages, practical examples, suggestions for further reading and exercises complete with detailed solutions. There is an emphasis on the principles and application of statistics without the use of algebra.The statistical material is strongly rooted in practical examples drawn from a wide range of journal articles representing both dental health care delivery and clinical dentistry. The perspective is international, with papers drawn from a variety of settings around the world. Many articles are recent and report contemporary developments in dental care.The intended audience includes dental students and practitioners, those engaged in dental research and other health care professionals. For students and tutors, it covers the undergraduate curriculum, and the exercises and solutions make it ideal for course use. For practitionerTrade Review"The author, who has a long track record of communicating statistics to non-experts, has for over 20 years steeped himself in the world of dental health care. The fruits of his experience are demonstrated by the rich set of examples which he brings to every chapter of the book. The subject matter of each chapter are applicable to any field involving statistical reasoning, but the authoritative way in which he relates every piece of teaching to realistic questions for dental care practitioners is most convincing. Previous generations of the dental community who have attempted to learn statistics have often had to turn to medical statistics textbooks. However, Smeeton has managed to break this mould and demonstrate properly the application of statistics in dentistry. His treatment of statistical concepts is orthodox and sound, but this third edition of the book has evolved to meet changing needs of the intended audience, including a welcome chapter on evidence-based dentistry. I anticipate many undergraduate and postgraduate dental students will find this book to be their primary source for their use of statistics."—Richard Morris, Professor in Medical Statistics, University of Bristol"The first edition of Nigel Smeeton’s highly accessible guide to research design and statistics was a breakthrough in providing a simple and easy to read guide to conducting research studies in dentistry. And now this third edition, which comprises 18 chapters, spans the principles of research design, broad aspects of the ethics of research, principles of statistical analysis and the appraisal of research (including peer review of manuscripts). Each chapter provides an introduction to the topic it will address which outlines the importance of the topic and the areas that will be covered, this is followed by the main body of the chapter, and is concluded with a short test for the reader to appraise their own learning. The author draws extensively on published dental research to provide examples. The most remarkable aspect of this book is that there is so little mathematics in it. The focus of the learning is understanding how statistics work without delving into the formulae. The third edition brings a new chapter on evidence based dental practice which is becoming increasingly important for policy and practice. There are also some new sections on advanced techniques – which with the increased availability of statistical software are being used more widely.There is little doubt that this is a very useful book for undergraduate dental students learning the skills of research design and critical appraisal of scientific research which will form part of the foundation for their future learning and continuing professional development. Throughout the text the key learning points are emphasised, and there are exercises to test the new learning. I would strongly recommend it for undergraduate courses. However I also believe it will be very useful for qualified practitioners who are keen to develop an awareness of statistical issues, in order to support an evidence-based approach to dental practice."–J T Newton, King’s College London Dental InstituteTable of ContentsPreface Preface to the second edition Preface to the first edition Introduction Planning a study Types of study in dental research Sampling Randomised controlled trials Ethical considerations The Normal distribution Diagnostic tests Sampling variation Introduction to hypothesis tests Comparing two means Dealing with proportions and categorical data Comparing several means Regression, correlation and agreement Non-Normally distributed data The choice of sample size Evidence based dentistry Statistical refereeing Appendix Solutions to exercises Index

Penguin Books Ltd The Drunkards Walk
Book SynopsisLeonard Mlodinow''s The Drunkard''s Walk: How Randomness Rules Our Lives is an exhilarating, eye-opening guide to understanding our random world.Randomness and uncertainty surround everything we do. So why are we so bad at understanding them? The same tools that help us understand the random paths of molecules can be applied to the randomness that governs so many aspects of our everyday lives, from winning the lottery to road safety, and reveals the truth about the success of sporting heroes and film stars, and even how to make sense of a blood test.The Drunkard''s Walk reveals the psychological illusions that prevent us understanding everything from stock-picking to wine-tasting - read it, or risk becoming another victim of chance.''A wonderfully readable guide to how the mathematical laws of randomness affect our lives'' Stephen Hawking, author of A Brief History of TimeTrade Review'Mlodinow writes in a breezy style, interspersing probabilistic mind-benders with portraits of theorists ! The result is a readable crash course in randomness.' New York Times 'If you're strong enough to have some of your favorite assumptions challenged, please read the Drunkard's Walk, a history, explanation, and exaltation of probability theory.'

Penguin Books Ltd The Numbers Game
Book SynopsisDiscover football''s astonishing hidden rules in The Numbers Game by Chris Anderson and David Sally*Fully updated with a new World Cup chapter* Football has always been a numbers game: 4-4-2, the big number 9 and 3 points for a win. But what if up until now we''ve been focusing on the wrong numbers? What if the numbers that really matter, the ones that hold the key to winning matches, are actually 2.66, 53.4, 50/50, and 0 > 1? What if managers only make a 15% difference? What if Chelsea should have bought Darren Bent?In this incisive, myth-busting book, Chris Anderson, former goalkeeper turned football statistics guru, and David Sally, former baseball pitcher turned behavioural economist, show that every shred of knowledge we can gather can help us to love football and understand it even more. You''ll discover why stopping a goal is more valuable than scoring one, why corners should be taken short, and why it is better to improve yTrade ReviewDoes the impossible of making the beautiful game even more beautiful -- Malcolm GladwellA must-read . . .

Book SynopsisWe are the safest humans who ever lived - the statistics prove it. And yet the media tells a different story with its warnings and scare stories. How is it possible that anxiety has become the stuff of daily life?In this ground-breaking, compulsively readable book, Dan Gardner shows how our flawed strategies for perceiving risk influence our lives, often with unforeseen and sometimes-tragic consequences. He throws light on our paranoia about everything from paedophiles to terrorism and reveals how the most significant threats are actually the mundane risks to which we pay little attention.Speaking to psychologists and scientists, as well as looking at the influence of the media and politicians, Gardner uncovers one of the central puzzles of our time: why are the safest people in history living in a culture of fear?Trade ReviewExcellent ... Gardner analyses everything from the media's predilection for irrational scare stories to the cynical use of fear by politicians pushing a particular agenda ...

Penguin Books Ltd The Signal and the Noise
Book SynopsisThe International Bestseller by ''The Galileo of number crunchers'' (Independent)Every time we choose a route to work, decide whether to go on a second date, or set aside money for a rainy day, we are making a prediction about the future. Yet from the financial crisis to ecological disasters, we routinely fail to foresee hugely significant events, often at great cost to society. The rise of ''big data'' has the potential to help us predict the future, yet much of it is misleading, useless or distracting.In The Signal and the Noise, the New York Times political forecaster Nate Silver, who accurately predicted the results of every state in the 2012 US election, reveals how we can all develop better foresight in an uncertain world. From the stock market to the poker table, from earthquakes to the economy, he takes us on an enthralling insider''s tour of the high-stakes world of forecasting, showing how we can all learn to detect the true signals amid a noise of data.

The University of Chicago Press Probably Overthinking It
Book SynopsisAn 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 pitfallslike the base rate fallacy, length-biased sampling, and Simpson's paradoxand 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 statisticsor if you have and forgot everything you learnedthis book will offer new insight into the methods and measurements that help us understand the world.Trade Review“Downey’s pure love for the subject shines through abundantly, as does his social conscience and belief in the importance of statistical methods to illuminate the greatest, most challenging issues of our time.” -- Aubrey Clayton, author of Bernoulli’s Fallacy: Statistical Illogic and the Crisis of Modern Science“Probably Overthinking It shows how fascinating and interesting statistics can be. Readers don’t need to be expert mathematicians. They just need to bring their curiosity about the world.” -- Ravin Kumar, data scientist at Google“Probably Overthinking It is a delightful exposition of commonly-encountered statistical fallacies and paradoxes and why they matter. The illustrations are powerful and the prose is exceptionally clear. There are few domains of human activity to which the lessons of this volume are not applicable.” -- Samuel H. Preston, coauthor of Demography: Measuring and Modeling Population Processes“Mark Twain once observed that ‘facts are stubborn things, but statistics are more pliable.’ Downey understands just how that happens, even to people who are not trying to obfuscate. It was an honest researcher who in 1971 found data that seemed to indicate smoking by pregnant women might be good for their babies—a misinterpretation that may have delayed anti-smoking measures by a decade. In this clear and cogent analysis, Downey explains why the data was misunderstood, as well as much else. It is a valuable book.” -- Floyd Norris, Johns Hopkins University, former chief financial correspondent for the New York TimesTable of ContentsIntroduction 1. Are You Normal? Hint: No 2.

Springer International Publishing AG Advanced Statistics for the Behavioral Sciences:
Book SynopsisThis book demonstrates the importance of computer-generated statistical analyses in behavioral science research, particularly those using the R software environment. Statistical methods are being increasingly developed and refined by computer scientists, with expertise in writing efficient and elegant computer code. Unfortunately, many researchers lack this programming background, leaving them to accept on faith the black-box output that emerges from the sophisticated statistical models they frequently use. Building on the author’s previous volume, Linear Models in Matrix Form, this text bridges the gap between computer science and research application, providing easy-to-follow computer code for many statistical analyses using the R software environment. The text opens with a foundational section on linear algebra, then covers a variety of advanced topics, including robust regression, model selection based on bias and efficiency, nonlinear models and optimization routines, generalized linear models, and survival and time-series analysis. Each section concludes with a presentation of the computer code used to illuminate the analysis, as well as pointers to packages in R that can be used for similar analyses and nonstandard cases. The accessible code and breadth of topics make this book an ideal tool for graduate students or researchers in the behavioral sciences who are interested in performing advanced statistical analyses without having a sophisticated background in computer science and mathematics.Table of ContentsLinear Equations.- Least Squares Estimation.- Linear Regression.- Eigen Decomposition.- Singular Value Decomposition.- Generalized Least Squares Estimation.- Robust Regression.- Model Selection and Biased Estimation.- Cubic Splines and Additive Models.- Nonlinear Regression and Optimization.- Generalized Linear Models.- Survival Analysis.- Time Series Analysis.- Mixed Effects Models.

Book SynopsisMaking good decisions under conditions of uncertainty - which is the norm - requires a sound appreciation of the way random chance works. As analysis and modelling of most aspects of the world, and all measurement, are necessarily imprecise and involve uncertainties of varying degrees, the understanding and management of probabilities is central to much work in the sciences and economics. In this Very Short Introduction, John Haigh introduces the ideas of probability and different philosophical approaches to probability, and gives a brief account of the history of development of probability theory, from Galileo and Pascal to Bayes, Laplace, Poisson, and Markov. He describes the basic probability distributions, and goes on to discuss a wide range of applications in science, economics, and a variety of other contexts such as games and betting. He concludes with an intriguing discussion of coincidences and some curious paradoxes. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

Cambridge University Press An Introduction to Probabilistic Number Theory
Book SynopsisDespite its seemingly deterministic nature, the study of whole numbers, especially prime numbers, has many interactions with probability theory, the theory of random processes and events. This surprising connection was first discovered around 1920, but in recent years the links have become much deeper and better understood. Aimed at beginning graduate students, this textbook is the first to explain some of the most modern parts of the story. Such topics include the Chebychev bias, universality of the Riemann zeta function, exponential sums and the bewitching shapes known as Kloosterman paths. Emphasis is given throughout to probabilistic ideas in the arguments, not just the final statements, and the focus is on key examples over technicalities.

Springer Verlag, Singapore Introduction to Stochastic Calculus
This book sheds new light on stochastic calculus, the branch of mathematics that is most widely applied in financial engineering and mathematical finance. The first book to introduce pathwise formulae for the stochastic integral, it provides a simple but rigorous treatment of the subject, including a range of advanced topics. The book discusses in-depth topics such as quadratic variation, Ito formula, and Emery topology. The authors briefly addresses continuous semi-martingales to obtain growth estimates and study solution of a stochastic differential equation (SDE) by using the technique of random time change. Later, by using Metivier–Pellaumail inequality, the solutions to SDEs driven by general semi-martingales are discussed. The connection of the theory with mathematical finance is briefly discussed and the book has extensive treatment on the representation of martingales as stochastic integrals and a second fundamental theorem of asset pricing. Intended for undergraduate- and beginning graduate-level students in the engineering and mathematics disciplines, the book is also an excellent reference resource for applied mathematicians and statisticians looking for a review of the topic.

Stata Press A Gentle Introduction to Stata, Revised Sixth
Book SynopsisAlan C. Acock's A Gentle Introduction to Stata, Revised Sixth Edition is aimed at new Stata users who want to become proficient in Stata. After reading this introductory text, new users will be able to not only use Stata well but also learn new aspects of Stata.Acock assumes that the user is not familiar with any statistical software. This assumption of a blank slate is central to the structure and contents of the book. Acock starts with the basics; for example, the part of the book that deals with data management begins with a careful and detailed example of turning survey data on paper into a Stata-ready dataset. When explaining how to go about basic exploratory statistical procedures, Acock includes notes that will help the reader develop good work habits. This mixture of explaining good Stata habits and explaining good statistical habits continues throughout the book.Acock is quite careful to teach the reader all aspects of using Stata. He covers data management, good work habits (including the use of basic do-files), basic exploratory statistics (including graphical displays), and analyses using the standard array of basic statistical tools (correlation, linear and logistic regression, and parametric and nonparametric tests of location and dispersion). He also successfully introduces some more advanced topics such as multiple imputation and multilevel modeling in a very approachable manner. Acock teaches Stata commands by using the menus and dialog boxes while still stressing the value of Stata commands and do-files. In this way, he ensures that all types of users can build good work habits. Each chapter has exercises that the motivated reader can use to reinforce the material.The tone of the book is friendly and conversational without ever being glib or condescending. Important asides and notes about terminology are set off in boxes, which makes the text easy to read without any convoluted twists or forward referencing. Rather than splitting topics by their Stata implementation, Acock arranges the topics as they would appear in a basic statistics textbook; graphics and postestimation are woven into the material naturally. Real datasets, such as the General Social Surveys from 2002, 2006, and 2016, are used throughout the book.The focus of the book is especially helpful for those in the behavioral and social sciences because the presentation of basic statistical modeling is supplemented with discussions of effect sizes and standardized coefficients. Various selection criteria, such as semipartial correlations, are discussed for model selection. Acock also covers a variety of commands available for evaluating reliability and validity of measurements.The revised sixth edition is fully up to date for Stata 17, including updated discussion and images of Stata's interface and modern command syntax. In addition, examples include new features such as the table command and collect suite for creating and exporting customized tables as well as the option for creating graphs with transparency.Table of ContentsGetting started Entering data Preparing data for analysis Working with commands, do-files, and results Descriptive statistics and graphs for one variable Statistics and graphs for two categorical variables Tests for one or two means Bivariate correlation and regression Analysis of variance Multiple regression Logistic regression Measurement, reliability, and validity Structural equation and generalized structural equation modeling Working with missing values—multiple imputation An introduction to multilevel analysis Item response theory (IRT) What’s next?

Springer-Verlag New York Inc. Basic Business Statistics A Casebook Textbooks in
Book SynopsisPreface Statistics is seldom the most eagerly anticipated course of a business student. Our goal in writing this casebook and the companion volume (Business Analysis Using Regression) was to change that impression by showing how statistics yields insights and answers interesting business questions.Trade Review"The manuscripts are divided into "classes" which tackle various statistical concepts. Material becomes increasingly complex as the data in later sections exhibit multiple deviations from ideal conditions. The casebooks use a combination of explanatory text and software output to guide the student. Almost no mathematics appears in these volumes; the authors make traditional texts available to their students who are curious about the technical details...I anticipate students will wholeheartedly endorse the FSW casebooks. The material is easy to digest as, for instance, the authors cleverly interweave probability, the standard error of the mean, and control charts. The casebooks effectively relay the message that statistics is relevant and doable. Ideally, that is the message that should be sent in all introductory business statistics courses."

Transworld Publishers Ltd The Improbability Principle
Book SynopsisWhy is it that incredibly unlikely phenomena actually happen quite regularly and why should we, in fact, expect such things to happen? Here, in this highly original book - aimed squarely at anyone with an interest in coincidences, probability or gambling - eminent statistician David Hand answers this question by weaving together various strands of probability into a unified explanation, which he calls the improbability principle.This is a book that will appeal not only to those who love stories about startling coincidences and extraordinarily rare events, but also to those who are interested in how a single bold idea links areas as diverse as gambling, the weather, airline disasters and creative writing as well as the origin of life and even the universe. The Improbability Principle will change your perspective on how the world works and tell you what the Bible code and Shakespeare have in common, how to win the lottery, why Apple''s song shuffling was made less random to seem more random. Oh and why lightning does in fact strike twice...Trade ReviewA hugely entertaining eye-opener about how misuse of statistics can skew our view of the world * Daily Mail *Lively and lucid . . . an intensely useful (as well as a remarkably entertaining) book . . . * Salon *In my experience, it is very rare to find a book that is both erudite and entertaining. Yet The Improbability Principle is such a book. Surely this cannot be due to chance alone! -- Hal Varian, Google’s Chief EconomistAn elegant, astoundingly clear and enjoyable combination of subtle statistical thinking and real-world events. -- Andrew Dilnot, co-author of 'The Numbers Game'As someone who happened to meet his future wife on a plane, on an airline he rarely used, I wholeheartedly endorse David Hand’s fascinating guide to improbability, a subject which affects the lives of all, yet until now has lacked a coherent exposition of its underlying principles. -- Gordon Woo, catastrophist at Risk Management Solutions

Taylor & Francis Ltd A First Course in Ergodic Theory
Book SynopsisA First Course in Ergodic Theory provides readers with an introductory course in Ergodic Theory. This textbook has been developed from the authorsâ own notes on the subject, which they have been teaching since the 1990s. Over the years they have added topics, theorems, examples and explanations from various sources. The result is a book that is easy to teach from and easy to learn from â designed to require only minimal prerequisites.Features Suitable for readers with only a basic knowledge of measure theory, some topology and a very basic knowledge of functional analysis Perfect as the primary textbook for a course in Ergodic Theory Examples are described and are studied in detail when new properties are presented. Trade Review"A First Course in Ergodic Theory by Dajani and Kalle provides not only a crystal clear introduction to the core of ergodic theory, but also goes down paths previously accessible only through the research literature. The book covers ergodic theorems, invariant measures, entropy and the variational principle. But it also covers piecewise monotone interval maps, Perron-Frobenius operators, natural extensions, and the useful lemma of Knopp. Another theme is the theory of conservative nonsingular and infinite measure preserving transformations. All of this is illustrated via numerous examples from (not necessarily regular) continued fractions and other number expansions, the authors’ specialty. Throughout the book, the proofs patiently explain details often ignored. An excellent appendix provides a reference to needed results from topology, measure theory, probability and functional analysis."– E. Arthur (Robbie) Robinson, Jr., Professor of Mathematics at George Washington University and co-author of The Mathematics of Politics"This textbook is a delightful introduction to Ergodic Theory. It starts at a basic level, giving intuitive explanations and motivations, and concludes with more advanced topics such as variational principle and infinite ergodic theory. The style is very crisp, and many of the results are proved. Examples which are primarily taken from number theory run as a red thread through the manuscript. This makes this textbook quite different from other classic textbooks on the subject. It’s very easy to build an advanced UG or a postgraduate lecture course around this material."– Sebastian van Strien, Imperial College LondonTable of ContentsPreface. Author Bios. 1.

CRC Press Tidy Finance with Python
Book SynopsisThis textbook shows how to bring theoretical concepts from finance and econometrics to the data. Focusing on coding and data analysis with Python, we show how to conduct research in empirical finance from scratch. We start by introducing the concepts of tidy data and coding principles using pandas, numpy, and plotnine. Code is provided to prepare common open-source and proprietary financial data sources (CRSP, Compustat, Mergent FISD, TRACE) and organize them in a database. We reuse these data in all the subsequent chapters, which we keep as self-contained as possible. The empirical applications range from key concepts of empirical asset pricing (beta estimation, portfolio sorts, performance analysis, Fama-French factors) to modeling and machine learning applications (fixed effects estimation, clustering standard errors, difference-in-difference estimators, ridge regression, Lasso, Elastic net, random forests, neural networks) and portfolio optimization techniques.Key Feature

With one hundred worked examples, the textbook guides students through statistical practice using real data and avoids complicated mathematics. Numerous end-of-chapter exercises allow students to apply and test their understanding of chapter topics, with detailed answers available online. The third edition has been updated throughout and includes a new chapter on research design, new topics (including weighted mean, resampling with the bootstrap, the role of the syntax file in workflow management, and regression to the mean) and new examples and exercises. Student learning is supported by a rich suite of online resources, including answers to end-of-chapter exercises, real data sets, PowerTrade Review'This is the third edition of a very popular and useful text. The focus is on using SPSS in the research process. The chapters have illustrative exercises and meaningful real data problem sets that not only make it convenient for teaching but also provide realistic experiences for students that will stay with them for many years. The book does a very good job presenting the challenge of data analysis and the experience of being a serious researcher looking at important problems; it illustrates how a variety of quantitative methods can be applied to real data to tease out and evaluate the inferences suggested by that data. I strongly recommend this book to instructors of a one- or two-semester introductory statistics course.' Robert W. Lissitz, University of Maryland'This text by Weinberg and Abramowitz is an excellent choice for an undergraduate or introductory graduate course for non-majors. Stressing concepts over computation, it focuses on essential material for students in education and the social sciences. The book reads easily, like a set of well-constructed lectures that begin with simple fundamental concepts. Yet modern and relatively advanced topics, such as uses of the bootstrap, are also treated. Rather than focusing on hand calculations, the book integrates instruction on using SPSS directly into the text. This enables student exploration of actual research data sets, beginning in the first chapters.' James E. Corter, Columbia University'This book covers a broad range of topics in introductory statistics, employing a hands-on, problem-based approach. The latest edition expands an already long list of topics to include bootstrap techniques and experimental design considerations. By providing detailed, worked-through examples based on real data and substantive research questions, the authors guide the student through the data analysis process from beginning to end. However, this is no 'cookbook' - each section builds on the concepts and techniques established previously, and the reader is encouraged to explore the nuances involved in effective statistical analysis. What is particularly unique about the authors' exposition is that it can be read on many levels; this book will serve well as a course textbook or as a handy reference for the applied researcher.'

Definitely recommended." ~Carl Howe, Director of Education, RStudio"The book can provide a good starting point into working with R. It covers a lot of perspectives that are expected in newsrooms all over the world, especially working with geospatial data. It also provides a lot of good examples and interesting additional resources. The packages used are also mainly part of the standard corpus of R-packages." ~Benedict Witzenberger, Süddeutsche Zeitung"I am the data editor of a mid-sized newsroom. I have long wished for an Intro to R book that was geared toward journalists, not data scientists. I’ve found that fellow journalists are much more likely to pick up on the intricacies of a computing language like R when they encounter it through a relatable example, like visualizing Election Night votes or analyzing a city council budget. Additionally, there are some R functions that simply aren’t useful for the quantitative needs of most journalists. This is what I appreciated the most about the book – its practical nature (the title doesn’t lie!) Machlis focuses on the concepts that data journalists most frequently encounter and spends little to no time on those they don’t…I also appreciated Chapter 17, "An R Project from Start to Finish." This chapter is exactly why I’ve wanted a journalism-specific Intro to R project that I can recommend to my colleagues" ~Ryann Jones, Deputy Editor, Data at ProPublica"I like the book. It’s conversationally written, it walks you through common problems in data journalism and for the most part uses the most common libraries to analyze and visualize data…The book’s instructional approach is the real value – it seems aimed at an audience that needs a narrative in order to understand code and analysis. Conveniently, that pretty well describes journalism students and working professionals…I would recommend publication. It advances the field of data journalism and presents a solid text for instructors or practitioners who are interested in R for analysis." ~Matthew Waite"I NEED THIS BOOK. I may adopt it as a textbook." ~Alberto Cairo, University of Miami"I’m reading this book now and it is terrific. Highly recommended for anyone interested in learning R. I will be using this book in my Data Analysis for Journalists class in the spring." ~Rob Wells, University of Arkansas"Sharon Machlis' 'Practical R for Mass Communication and Journalism' is based on the author's workshops for journalists. This book dives straight into doing the kinds of things a busy reporter or news analyst needs to do to meet a 5:00 pm deadline: data cleaning, presentation-quality graphics, and maps take precedence over control flow or the niceties of variable scope. I particularly enjoyed the way each chapter starts with a realistic project and works through what's needed to build it. People who've never programmed before will be a little intimidated by how many packages they need to download if they try to work through the material on their own, but the instructions are clear, and the author's enthusiasm for her material shines through in every example." ~Greg Wilson, RStudio"Practical R for Mass Communication and Journalism looks to me like a fabulous resource for those folks who always wanted to learn some more R but were afraid to ask. Definitely recommended." ~Carl Howe, Director of Education, RStudio"The book can provide a good starting point into working with R. It covers a lot of perspectives that are expected in newsrooms all over the world, especially working with geospatial data. It also provides a lot of good examples and interesting additional resources. The packages used are also mainly part of the standard corpus of R-packages." ~Benedict Witzenberger, Süddeutsche Zeitung"I am the data editor of a mid-sized newsroom. I have long wished for an Intro to R book that was geared toward journalists, not data scientists. I’ve found that fellow journalists are much more likely to pick up on the intricacies of a computing language like R when they encounter it through a relatable example, like visualizing Election Night votes or analyzing a city council budget. Additionally, there are some R functions that simply aren’t useful for the quantitative needs of most journalists. This is what I appreciated the most about the book – its practical nature (the title doesn’t lie!) Machlis focuses on the concepts that data journalists most frequently encounter and spends little to no time on those they don’t…I also appreciated Chapter 17, "An R Project from Start to Finish." This chapter is exactly why I’ve wanted a journalism-specific Intro to R project that I can recommend to my colleagues" ~Ryann Jones, Deputy Editor, Data at ProPublica"I like the book. It’s conversationally written, it walks you through common problems in data journalism and for the most part uses the most common libraries to analyze and visualize data…The book’s instructional approach is the real value – it seems aimed at an audience that needs a narrative in order to understand code and analysis. Conveniently, that pretty well describes journalism students and working professionals…I would recommend publication. It advances the field of data journalism and presents a solid text for instructors or practitioners who are interested in R for analysis." ~Matthew Waite"I NEED THIS BOOK. I may adopt it as a textbook." ~Alberto Cairo, University of Miami"I’m reading this book now and it is terrific. Highly recommended for anyone interested in learning R. I will be using this book in my Data Analysis for Journalists class in the spring." ~Rob Wells, University of Arkansas"Sharon Machlis' 'Practical R for Mass Communication and Journalism' is based on the author's workshops for journalists.
