Definitions:

Independent Sample Variances

A measure of the variability in each of two or more independent samples, used in hypothesis testing to assess the assumption of equal variances.

Normal Populations

Populations that are distributed in a way that forms a symmetrical, bell-shaped curve when graphed, with most members being close to the average.

Equal Variances

The assumption that two or more groups have the same variance, often used in t-tests and ANOVAs.

F Distribution

A probability distribution used in analysis of variance (ANOVA), among other methods, that is right-skewed and originates from the ratio of two chi-squared distributions.
