Cricket

batting averages, run rate

A batsman's career average, strike-rate distribution, win-probability — every stat shown on screen is descriptive statistics in real time.

Polls

predicting election outcomes

Election surveys quote "42% ± 3% margin of error" — that's the standard error of a sample proportion.

Medicine

clinical trial efficacy

Drug trials report p-values; "significant at p < 0.05" means the observed effect would happen by chance less than 5% of the time.

Business

A/B testing for websites

A/B testing on websites uses Bayesian statistics to declare a winning button colour after enough samples. Amazon does thousands of these per week.

Insurance

risk pricing

Actuaries fit mortality curves and accident-frequency distributions — premiums are expected-loss + risk loading, both statistical quantities.

Quality control

manufacturing tolerance

Six Sigma manufacturing keeps defects below 3.4 per million by monitoring process mean and standard deviation on control charts.
