Definitions:

Population Variances

A measure of the spread or dispersion of a set of data points in a population, indicating how much the members of the population differ from the population mean.

Normally Distributed

Describes a probability distribution that is symmetrical around the mean, with a specific bell shape indicating that data near the mean are more frequent in occurrence than data far from the mean.

Sample Variances

Measures of the dispersion or spread within a set of sample data, quantifying how much the samples differ from each other.

Test Statistic

A calculated value from sample data used to determine if a hypothesis about a population parameter is supported.
