How to Avoid Being Misled by Statistics: Don't Be One of the 60% Who Are Below Average Mr John Harvey Murray 1.º edición

Three kinds of people ought to read this book. Firstly there are those who use statistics in their work: accountants, scientists, advertisers, marketers, politicians and journalists. If you are in one of these categories I would like to help you to maintain, or aspire to, a reasonable standard of honesty and integrity, so that people can trust what you say, and so that you do not even inadvertently mislead yourself as well as others. Secondly there are cynics who think statistics can never be trusted and are just tools used by liars. I want to show that they can be used properly, and also that with a little thought, we can all learn to spot the false or exaggerated claims, the non-sequitors, and the unsubstantiated assumptions. Then we will be able to see the truth when it appears. Thirdly, there are the huge number of ordinary people who get totally confused and sometimes, sadly, misled, by statistics. I want to help you make sense of what you read or hear, and be able to be confident in sorting the facts from the hype. It is for this third group that this book is really written. If the other two groups benefit, I will be glad, but if you are in this group, please read on. I hope you will enjoy it, but above all I hope it will empower you.
