News and Numbers: A Guide to Reporting Statistical Claims and Controversies in Health and Other Fields

'"News & Numbers" is a simple and nonmathematical 'how to' guide - how to understand and analyze and explain and do a better job of telling our audiences the truth' - Victor Cohn. Numbers and statistical claims are involved in nearly everything that journalists report. Science and medical issues, politics, business, crime analysis, sports - all demand numbers. This book helps the reader answer three key questions about all scientific studies, polls and other statistical claims: what can I believe? What does it mean? How can I explain it to others? The second edition of "News & Numbers" builds on the tradition set by the original book, emphasizing clear thinking and commonsense approaches for understanding, analyzing and explaining statistics.Terms are explained in easy-to-understand, nontechnical language. This updated edition contains new material in every chapter. New features include: a full chapter on polls and polling; sections on reporting disease outbreaks and evaluating managed health care plan; a section on focus groups; information on using the Internet; and dozens of new examples of numbers in the news. The late Victor Cohn was a science writer for the "Washington Post" for 25 years, serving part of the time as the science editor.
