Combine variance of multiple subpopulations (Scripts) Publisher's description
This function calculates the variance of a population using only the means
This function calculates the variance of a population using only the means, variances and number of observations of its subpopulations.
This means you do not need to keep all individual observations in each subpopulation to later find out the variance of the pooled data.
