Central Limit Theorem
The Central Limit Theorem is a statistical theory that states that the sampling distribution of the sample mean approaches a normal distribution, regardless of the population's distribution, given a large enough sample size.
Population
All members or elements under consideration in statistical studies make up this group.
Standard Error
A measure of the statistical accuracy of an estimate, calculated from the standard deviation of a sampling distribution.
Sample Size
The number of observations or replicates included in a statistical sample, crucial for the reliability and accuracy of the study or experiment.
