- Central limit theorem - Wikipedia
In probability theory, the central limit theorem (CLT) states that, under appropriate conditions, the distribution of a normalized version of the sample mean converges to a standard normal distribution This holds even if the original variables themselves are not normally distributed

The Central Limit Theorem in Statistics states that as the sample size increases and its variance is finite, then the distribution of the sample mean approaches the normal distribution, irrespective of the shape of the population distribution

The central limit theorem states that if you take sufficiently large samples from a population, the samples’ means will be normally distributed, even if the population isn’t normally distributed

This tutorial shares the definition of the central limit theorem as well as examples that illustrate why it works

So, in a nutshell, the Central Limit Theorem (CLT) tells us that the sampling distribution of the sample mean is, at least approximately, normally distributed, regardless of the distribution of the underlying random sample

The central limit theorem in statistics states that, given a sufficiently large sample size, the sampling distribution of the mean for a variable will approximate a normal distribution regardless of that variable’s distribution in the population
- Central Limit Theorem - Stanford University
In summary, the Central Limit Theorem explains that both the sample mean of IID variables is normal (regardless of what distribution the IID variables came from) and that the sum of equally weighted IID random variables is normal (again, regardless of the underlying distribution)

The central limit theorem is a theorem about independent random variables, which says roughly that the probability distribution of the average of independent random variables will converge to a normal distribution, as the number of observations increases
