Law of Large Numbers
The Law of Large Numbers is a fundamental theorem in probability theory that describes the tendency of the average of a large sample to converge to the expected value as the size of the sample increases. It states that as the number of trials or observations grows, the sample mean will approach the population mean. This principle underpins many statistical analyses and forms the basis of confidence in empirical results. Understanding the Law of Large Numbers is crucial in various fields such as finance, insurance, and quality control, where accurate predictions rely on statistical principles.
