In this world-famous book, Darrell Huff explains the many ways statistics can be misused to deceive audiences and manipulate their opinions. Every day you’re bombarded with attempts to push you into buying some “necessary” product or choosing the “right” candidate: “Thanks to ‘Clean Teeth’ toothpaste, tooth decay decreases by 23%!”; “N policy supports 85% of citizens”… How can you tell whether particular data are reliable? How are the calculations made? What’s taken into account, and what stays out of view? The author reveals the secret tools statisticians use and equips the reader with knowledge that will help you untangle all the intricacies of this science—and prevent you from being misled.
