WebOct 10, 2024 · Example: Central limit theorem – mean of a small sample. mean = (68 + 73 + 70 + 62 + 63) / 5. mean = 67.2 years. Suppose that you repeat this procedure ten times, taking samples of five retirees, and calculating the mean of each sample. This is a sampling distribution of the mean.

In probability theory, the central limit theorem (CLT) establishes that, in many situations, for identically distributed independent samples, the standardized sample mean tends towards the standard normal distribution even if the original variables themselves are not normally distributed.
