Originating from 18th-century gambling mathematics pioneered by Abraham de Moivre and later formalized by Pierre-Simon Laplace, the theorem states that averaging many independent random outcomes always produces a normal distribution, regardless of the underlying distribution. This makes it foundational to modern statistics and empirical science, enabling researchers to draw confident conclusions from measurements. The theorem has limits — it requires many independent samples — and extreme events may matter more than averages in some contexts, but variants of the theorem extend its power across many statistical problems. ## Full article daily.dev links to this article rather than hosting it.
