Part of the Against All Odds: Inside Statistics Series. This episode focuses on taking samples and forming a conclusion based on sample response. The census is a perfect real-life example to illustrate consensus and sampling. Statisticians also use sampling from a population as an alternative to a complete count, as shown by visiting a potato chip factory.
