Definitions:

Degrees Of Freedom

Degrees of freedom represent the number of independent values or quantities which can freely vary in an analysis without violating any constraints imposed on them.

Pooled Variance

A method used to estimate the variance of two or more populations when the mean of each population may differ but the true variance is assumed to be the same.

Standard Error

The typical deviation found within the distribution of samples for a statistic, usually referring to the mean.

Independent Samples

Independent samples refer to two or more groups of data that are collected from separate, non-overlapping populations, ensuring they are not influenced by each other.
