In probability theory, the central limit theorem clt establishes that, in some situations, when independent random variables are added, their properly normalized sum tends toward a normal distribution informally a bell curve even if the original variables themselves are not normally distributed. For example, the graphical illustration of the approximation of the standardized binomial distributions to the normal curve is a more convincing demonstration of the central limit theorem than many of the formal proofs of this fundamental result.
