## FAQ

The sample variance, s², is used to calculate how varied a sample is. In statistics, a data sample is a set of data collected from a population. Typically, the population is very large, making a complete enumeration of all the values in the population impossible. The solution is to take a sample of the population with manageable size, say 5,000, and use that sample to calculate statistics.

The sample variance is calculated by following formula: Where:
s2 = sample variance
x1, ..., xN = the sample data set
x̄ = mean value of the sample data set
N = size of the sample data set
