Definitions:

T Distribution

A probability distribution that is used in hypothesis testing for small sample sizes, when the population standard deviation is unknown.

Normal Distribution

A probability distribution that is symmetric around the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Confidence Interval

A range of values, derived from sample statistics, that is likely to contain the value of an unknown population parameter with a certain level of confidence.

Confidence Level

The probability or percentage that a parameter lies within a specified range of values, indicating the degree of certainty about a statistical estimate.
