Two very important theorems in statistics are the Law of Large Numbers and the Central Limit Theorem. It is important in Statistics because it guarantees that, when it applies, the samples that are drawn are always randomly selected. Simple Random Samples From a Table of Random Digits, Example of Confidence Interval for a Population Variance, How to Do Hypothesis Tests With the Z.TEST Function in Excel, Bell Curve and Normal Distribution Definition, B.A., Mathematics, Physics, and Chemistry, Anderson University. Notify me of follow-up comments by email. This theorem allows you to simplify problems in statistics by allowing you to work with a distribution that is approximately normal. Although the central limit theorem can seem abstract and devoid of any application, this theorem is actually quite important to the practice of statistics. the sample distribution has higher tendency to follow the normal distribution. Even if the concerned population has a tilted distribution, especially when things such as incomes or people's weights are being examined, the sampling distribution for a sample with an adequately large sample size will remain normal.

So, since we can approximate a̶n̶y̶ a lot of distributions with a Normal distribution (under a certain conditions), Central Limit Theorem is very useful for analyzing many distribution out there in the world. The central limit theorem forms the basis of the probability distribution. The statement of the central limit theorem can seem quite technical but can be understood if we think through the following steps. Although there is no one complete central limit theorem definition, here is the one commonly found in most statistics textbooks.“The Central Limit Theorem (CLT) is a It is a powerful statistical concept that every data scientist MUST know.  (CLT). One of my teacher in Probability once told us that this name (Central Limit Theorem) was just used (at the beginning) to stress the importance of the result -which plays a central role in the theory.
