Law of Large Numbers

lɔː əv lɑrdʒ ˈnʌmbərz

The Law of Large Numbers is a fundamental theorem in probability and statistics that describes the result of performing the same experiment a large number of times. It states that as the number of trials increases, the sample mean will converge to the expected value. This principle is crucial in various fields, including data science and machine learning, where it ensures that larger datasets yield more reliable estimates. Common use cases include quality control, risk assessment, and predictive modeling, where consistent outcomes are desired from repeated measurements or experiments.
