Definitions:

Normal Distribution

A distribution pattern in probabilities that is balanced around the mean, signifying that data points near the mean have a higher frequency of occurrence compared to those far from the mean.

T Distribution

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

Degrees of Freedom

The number of independent values or quantities which can vary in an analysis without breaking any constraints.

T Distribution

A probability distribution that is used to estimate population parameters when the sample size is small and the population variance is unknown.
