Central Limit Theorem Definition

  • Central limit theorem implies that the sum of independently distributed random variables is approximately normal, regardless of the distributions of the individual variables.

Central Limit Theorem Explanation

An important concept in statistics and probability is central limit theorem. Central limit theorem is linked with sample means. This theorem states that even if the data values are non-normal, the distribution of sample means will be approximately normal. The central limit theorem is valid for large sample sizes. It shows that for large sample sizes the sample probability distribution tend to become normal regardless of the probability distribution of the population. As large sample size is the key in this theorem, the size of the sample depends on two factors; requirement for accuracy, and shape of the population distribution.
