Why statistics matter and how they mislead, describing data with averages and spread, percentages, rates and risks, how samples and surveys work, why correlation is not causation and how researchers find causes, probability and risk in everyday life, misleading charts and paradoxes, and a simple set of questions for checking any statistic yourself.

The aim is confidence, not suspicion: you should finish able to read a news story, a poll or a health claim with a calm, questioning eye, do the simple arithmetic that exposes a misleading number, and explain your reasoning to others. No math beyond basic arithmetic is needed.
