Definitions:

T-Values

Statistics used in T-tests that compare the means of two groups. They indicate how many standard deviations an observed sample mean is from the null hypothesis mean.

Z-Values

Standardized scores that indicate how many standard deviations an element is from the mean.

Sample Size

The number of observations or data points used in a statistical sample.

Degrees Of Freedom

The number of independent values or quantities which can be assigned to a statistical distribution, often determining the shape of the distribution.
