The sample variance equation is a statistical formula used to calculate the variability of a dataset. It measures how much the individual data points deviate from the mean value. The formula is as follows:

Common questions about the sample variance equation

- n is the sample size

The sample variance equation calculates the variability of a dataset, whereas the population variance equation calculates the variability of the entire population. The main difference between the two is the use of the sample size (n-1) in the sample variance equation, which is not present in the population variance equation.

- σ^2 is the sample variance
