Grade 9 · Data & Probability
Statistics in Society
Statistics shape the news, advertising, and public policy — and they can mislead. Students learn the difference between a population and a sample, recognize biased sampling and misleading graphs, and weigh the ethics of how data is collected and reported. The goal is a critical citizen who asks 'who was asked, and how?' before trusting a number.
