Part I: Learning the Basics
Part II: Now Down to Specifics
Numbers and statistical claims dominate today's news. Politics, budgets, crime analysis, medical issues, and sports reporting all demand numbers. Now in its third edition, News & Numbers focuses on how to evaluate statistical claims in science, health, medicine, and politics. It does so by helping readers answer three key questions about all scientific studies, polls, and other statistical claims: "What can I believe?" "What does it mean?" and "How can I explain it to others?"
Updated throughout, this long overdue third edition brings this classic text up-to-date with the 21st century with a complete updating of examples, case studies, and stories. The text emphasises clear thinking and common sense approaches for understanding, analyzing and explaining statistics, and terms throughout the book are explained in easy-to-understand, nontechnical language. Much new material has been added to ensure the text maintains its pertinent approach to the subject, including:
* A section on computer modelling
* Additional chapters on risks and 'missing numbers'
* Updated sections on health plans and insurance, including updates on President Obama's health system overhaul & new material on health care costs and quality
