      • Frequently Asked Questions

      So, what is sample variance, and how does it work? In simple terms, sample variance measures the amount of variation or dispersion in a set of data. It calculates the average distance between each data point and the mean, providing a quantitative measure of data spread. Think of it like measuring the distance between a set of dots on a number line. The farther apart the dots, the higher the sample variance.
