Population Variances

A measure of the dispersion of a population's values, quantifying how much the members of the population differ from the population mean.

Population Variances

A measure of the dispersion of a set of data points in a population, calculating the average of the squared differences from the mean.

Significance Level

The probability of rejecting the null hypothesis when it is true, often denoted by alpha.

Population Variances

A measure of the dispersion or spread of a set of data points in a population in terms of its mean, indicating how far the values lie from the average.
