The central limit theorem (CLT) is a fundamental concept in statistical theory, which states that the means of a sufficiently large number of samples of a random variable will be approximately normally distributed, no matter how the original population is distributed. The following are the symbols used to describe the central limit theorem (CLT) and their descriptions:

1. 𝓍̅: Refers to the sample mean. It is calculated by adding all of the observations in a sample and dividing by the sample size.

2. 𝑝̅: Refers to the population mean. It is calculated by adding all of the observations in the population and dividing by the population size.

3. 𝘯: Refers to the sample size. The larger the sample size, the more reliable the sample mean will be as an estimate of the population mean.

4. 𝜇: Refers to the population standard deviation. It is a measure of the amount of variation in the population. The larger the standard deviation, the more spread out the data.

The central limit theorem allows statisticians to apply normal distribution models to real-world data, even if that data is not normally distributed. It is an essential tool in statistical analysis, allowing us to make inferences about populations based on the results of samples.
