Definitions:

Degrees Of Freedom

The count of the number of values in a calculation that are free to vary without infringing on the given data.

T-Distribution

A probability distribution that arises in the sampling distribution of sample means, especially useful when the sample size is small and the population standard deviation is unknown.

Normal Distribution

A bell-shaped curve where a large number of data points are symmetrically distributed around the mean, with fewer and fewer observations the further away from the mean.

Point Estimate

A single value or statistic that serves as the best guess or most reasonable approximation of a population parameter.
