This book shares the goal of the classic text How to Lie with Statistics, namely, preventing and correcting statistical misconceptions that are common among practitioners, though its focus is on the educational context. It illustrates and discusses the essentials of educational statistics that will help educational practitioners to do this part of their job properly, i.e., without making conceptual mistakes. The examples are cast in the school/classroom contexts, based on realistic rather than theoretical examples. “The strongest aspect of the work or author’s view is that the author can put himself in the shoes of teachers and make the work a very practical guide for teachers and school leaders. As a very experienced educator and researcher, the author knows very well about the knowledge skills that are essential for the professional development of teachers. He is able to explain the statistical and measurement concepts in plain language and with examples that are highly relevant to the target audience. In addition, the author also conveyed an important message to the target audience throughout the work... by pointing out the mistakes and misunderstandings of the interpretation of test scores and measurement design. The author reminds the audience about the importance of proper use of tests and test scores when teachers and school leaders make any education decisions, which has much implication on the professional integrity of teachers and school leaders.” Dr. Joyce Kwan, The Education University of Hong Kong, Hong Kong “This book covers all the statistical tools for analyzing educational data and provides examples to explain the ideas. Chapters 10-17 are practical data analysis in educational data that helps readers have a better understanding of the procedure to analyze the data.” Dr. Alpha Ling, The Education University of Hong Kong, Hong Kong “It looks like a very interesting book with attractive topics and practical problems in educational statistics. Though the topics remind me of the classic book How to Lie with Statistics, this book aims at preventing and correcting statistical misconceptions in educational context.” Dr. Zhu Ying, National Institute of Education, Nanyang Technological University, Singapore

The niche bestseller "Surviving Prostate Cancer Without Surgery" begins with the shooting of a urologist and includes a World War II Battle. The book exposes the big lie about radical prostate surgery, is filled with cartoons and simple diagrams, and is written for the average layperson in easy-to-understand style.The author, Bradley Hennenfent, M.D., has known many men who suffered from prostate cancer and his book includes many uplifting stories about less harmful treatments than surgery. Dr. Hennenfent also explains the problem of lies, damn lies, and prostate cancer statistics. The adverse effects of surgery: impotence, sexual dysfunction, incontinence, and urethral strictures are explained in realistic fashion.Urologist W. Reid Pitts, Jr., M.D., FACS, wrote an outstanding letter-to-the-editor of the "Journal of Urology" lambasting the radical prostatectomy. When interviewed for "Surviving Prostate Cancer Without Surgery," Dr. Pitts said: "Although I did the first ever nerve sparing radical prostatectomy at New York-Cornell Hospital, I've abandoned the radical prostatectomy for my prostate cancer patients. There is always a better treatment option.""Two randomized, controlled studies suggest that about 90% of all prostate cancer surgery done to date has failed to extend the life of the patient," says Dr. Bradley Hennenfent M.D., the book's author, who adds, "This will be news to most men.""Surgery should not be advertised as a cure-all for prostate cancer," says Dr. Hennenfent, "although surgery does increase the lifespan of about 10% of highly selected patients, and improvements in surgery are constantly being developed.""My book details the harm done by surgery, while explaining the pros and cons of watchful waiting, active surveillance, noninvasive therapy, radiation seed implants, three-dimensional radiation therapy, herbal medications, cryosurgery, and hormone blockade."

An interdisciplinary view of the evolution and consequences of flexible social cognition—the capacity to withhold the inference of mental states to other people. In Invisible Mind, Lasana Harris takes a social neuroscience approach to explaining the worst of human behavior. How can a person take part in racially motivated violence and then tenderly cradle a baby or lovingly pet a puppy? Harris argues that our social cognition—the ability to infer the mental states of another agent—is flexible. That is, we can either engage or withhold social cognition. If we withhold social cognition, we dehumanize the other person. Integrating theory from a range of disciplines—social, developmental, and cognitive psychology, evolutionary anthropology, philosophy, economics, and law—with neuroscience data, Harris explores how and why we engage or withhold social cognition. He examines research in these different disciplines and describes biological processes that underlie flexible social cognition, including brain, genetic, hormonal, and physiological mechanisms. After laying out the philosophical and theoretical terrain, Harris explores examples of social cognitive ability in nonhumans and explains the evolutionary staying power of this trait. He addresses two motives for social cognition—prediction and explanation—and reviews cases of anthropomorphism (extending social cognition to entities without mental states) and dehumanization (withholding it from people with mental states). He discusses the relation of social cognition to the human/nonhuman distinction and to the evolution of sociality. He considers the importance of social context and, finally, he speculates about the implications of flexible social cognition in such arenas for human interaction as athletic competition and international disputes.

Honesty is my moral compass, which is grounded and rooted upon a solid and stable foundation. My sense of integrity, self-worth, and self-confidence is not dependent on the outside world, but it is an internal feeling. This feeling cannot be emulated. You have to build one for yourself. Learn to focus on more than the outer appearance of things, and use a soft focus on the senses you have been divinely blessed with. Believe me, there is always much more to a story than meets the eye and ear. Listen to your breathing and heartbeat, and then you will become aware of the rhythms around you. Mix all of the ingredients with a hungry thirst for knowledge and a curious mind, and it will help you build your moral compass of honesty.

How to Lie with Numbers, Stats & Graphs is a book that contains two of our best sellers – and by far our funniest! In this eye-opening book, award-winning statistician and author Lee Baker uncovers the key tricks of the trade used by politicians, corporations and other statistical conmen to deceive, hoodwink and otherwise dupe the unwary. Blurb: Truth, Lies & Statistics Pirates, cats, Mexican lemons and North Carolina lawyers. Cheese consumption, margarine and drowning by falling out of fishing boats. This book has got it all. A roller coaster of a book in 8 witty chapters, this might just be the most entertaining statistics book you’ll read this year. Did you know that pirates caused global warming, and that a statistical lie gave rise to one of the fastest growing religions on the planet? Probably not – you might have missed the memo that day. Did you also know that organic food is the real cause of autism, and that Mexican lemons are a major cause of deaths on American roads? They’re true, honest – and this book has got the stats to prove it. In this eye-opening book, award winning statistician and author Lee Baker uncovers the key tricks of the trade used by politicians, corporations and other statistical conmen to deceive, hoodwink and otherwise dupe the unwary. Like how the ex-Chancellor of the Exchequer attempted to persuade us that 5 lots of 10 make 150, or how the President of the United States tried to convince us that 420,000 is a larger number than 782,000. Nice try boys, but we were awake that day! In his trademark sardonic style, the author reveals the secrets of how the statistical hustlers manipulate and misrepresent data for political or commercial gain – and often get away with it. Blurb: Graphs Don't Lie Sarah Palin, abortions, global warming and Usain Bolt. The CEO of Apple, 35 trillion gun deaths in 1995, Fox News and 193%. This book has got scandals galore! With 9 witty chapters taking you on a roller coaster tour of graphical lies, pictorial deceits and pie charts of mayhem, this might just be the most entertaining book about graphs you’ll read this year. Did you know that between them, Sarah Palin, Mike Huckabee and Mitt Romney enjoyed a total of 193% support from Republican candidates in the 2012 US primaries? It must be true – it was on a pie chart broadcast on Fox News. Did you also know that the number 34 is smaller than 14, and zero is much bigger than 22? Honest, it’s true, it was published in a respectable national newspaper after the 2017 UK General Election. There can’t have been any kind of misdirection here because they were all shown on a pie chart. In this astonishing book, award winning statistician and author Lee Baker uncovers how politicians, the press, corporations and other statistical conmen use graphs and charts to deceive their unwitting audience. Like how a shocking, and yet seemingly innocuous statement as “Every year since 1950, the number of children gunned down has doubled”, meant that there should have been at least 35 trillion gun deaths in 1995 alone, the year the quote was printed in a reputable journal. Or how an anti-abortion group made their point by trying to convince us all that 327,000 is actually a larger number than 935,573. Nice try, but no cigar – we weren’t born yesterday. In his trademark sardonic style, the author reveals the secrets of how the statistical hustlers use graphs and charts to manipulate and misrepresent for political or commercial gain – and often get away with it. Written as a layman’s guide to lying, cheating and deceiving with data, statistics and graphs, in this book there’s not a dull page in sight! And there are elephants too… Discover the exciting world of lying with data, statistics and graphs. Get this book, TODAY!
