T-Distribution

A type of probability distribution that is symmetric and bell-shaped, used in statistics for small sample sizes when the population variance is unknown.

Confidence Interval

A scope of values, derived through sample statistical methods, seen as likely to include the value of an unascertained population parameter.

Population Mean

The average of a set of numerical values obtained from every member of a population.
