Grand Mean

The grand mean is the mean of means, calculated by taking the average of the mean values from multiple groups or samples within the data.

Population Variances

A measure that indicates the degree to which individuals in a population vary or differ from the mean of the population.

Normally Distributed

Refers to a theoretical distribution whose random variable values are symmetrically distributed around the mean, having a specific bell-shaped curve.
