[Free Statistics Book] Know Your Chances – NCBI Bookshelf

Ever been scared or made uncomfortable about threats to your health? And solutions that seemed too good to be true?
Here’s a book for just about everyone that can help one understand the statistics behind health information. And how to spot misinformation easily.

What This Book is About – Know Your Chances – NCBI Bookshelf.

From the intro

Every day we are faced with news stories, ads, and public service announcements that describe health threats and suggest ways we can protect ourselves. It’s impossible to watch television, open a magazine, read a newspaper, or go online without being bombarded by messages about the dangers we face.

Many of the messages are intended to be scary, warning us that we are surrounded by danger and hinting that everything we do or neglect to do brings us one step closer to cancer, heart disease, and death. Other messages are intended to be full of hope, reassuring us that technological miracles and breakthrough drugs can save us all. And many messages do both: they use fear to make us feel vulnerable and then provide some hope by telling us what we can do (or buy) to lower our risk. In addition, as you may suspect, a great many of these messages are wildly exaggerated: many of the risks we hear about are really not so big, and the benefits of many of the miraculous breakthroughs are often pretty small.

As a result, we are often left misinformed and confused. But it doesn’t have to be that way.

The goal of this book is to help you better understand health information by teaching you about the numbers behind the messages—the medical statistics on which the claims are based. The book will also familiarize you with risk charts, which are designed to help you put your health concerns in perspective. By learning to understand the numbers and knowing what questions to ask, you’ll be able to see through the hype and find the credible information—if any—that remains.

Don’t worry: this is not a math book (only a few simple calculations are required). Instead, this is a book that will teach you what numbers to look for in health messages and how to tell when the medical statistics don’t support the message. This book will help you develop the basic skills you need to become a better consumer of health messages, and these skills will foster better communication between you and your doctor.
