WebFree Variance Calculator - find the Variance of a data set step-by-step WebThe variance is the average of the squared deviations about the mean for a set of numbers. The population variance is denoted by σ 2. It is given by the formula: The capital Greek letter sigma 𝚺 is commonly used in mathematics to represent a summation of all the numbers in a grouping. N is the number of terms in the population.

WebAboutTranscript. Population variance is a measure of how spread out a group of data points is. Specifically, it quantifies the average squared deviation from the mean. So, if all data points are very close to the mean, the variance will be small; if data points are spread out over a wide range, the variance will be larger. Created by Sal Khan.
