Definitions:

Standard Deviation

A measure of the amount of variation or dispersion of a set of values, indicating how much the values differ from the mean.

T-Distribution

A probability distribution used in statistics that arises when estimating the mean of a normally distributed population in situations where the sample size is small and population variance is unknown.

Confidence Interval

A range of values, derived from the sample data, that is believed, with a certain degree of probability, to contain the true population parameter.

Margin Of Error

An estimate of the amount by which an observed sample result may differ from the true value, providing a confidence interval for the estimation.
