Central Limit Theorem: A sampling distribution of the mean is approximately normally distributed if the sample size is sufficiently large. This is true no matter what the population distribution is.

What Is the Central Limit Theorem? The Central Limit Theorem (CLT) states that if you sample a data population enough times, then the means and standard deviations of the samples will approach a ...
