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.

"What does it mean?" and "How can I explain it to others?"
