Definitions:

Central Limit Theorem

A statistical theory that states the distribution of sample means approaches a normal distribution as the sample size becomes larger, regardless of the population's distribution.

Sampling Distribution

The configuration of probability for a given statistic, determined by a random sample.

Sample Mean

The average value calculated from a set of samples or observations drawn from a larger population.

Population Mean

The population mean is the average value of a population attribute, computed by summing all the values in the population and dividing by the total number of values.
