Law of Large Numbers

Probability and Statistics

In probability theory, the law of large numbers is a mathematical law stating that the average of the results obtained from a large number of independent, identically distributed random samples converges to the true expected value as the number of samples grows, provided that expected value exists. The result exists in two standard forms, the weak law and the strong law, which differ in the type of convergence they guarantee; this entity covers the general law encompassing both, which is why sample averages are treated as reliable estimates of a population mean.
