Quick Definition

The Central Limit Theorem (CLT) is a statistical principle that states that the distribution of sample means approximates a normal distribution as the sample size becomes larger, regardless of the population's distribution.

Formula

\bar{X} \approx N(\mu, \frac{\sigma^2}{n})

Examples

  • 1In investment risk assessment, CLT helps in determining the probability distribution of asset returns over time.
  • 2In banking, CLT is used to model the average number of transactions per customer to optimize service.
  • 3In insurance, actuaries use CLT to predict claim amounts and set premiums accordingly.
  • 4In market research, CLT assists in predicting consumer behavior by analyzing sample data from surveys.
