The variance and the closely-related standard deviation are measures of how spread out a distribution is. In other words, they are measures of variability. Calculating the variance is an important part of many statistical applications and analyses. It is the first step in calculating the standard deviation.

To calculate the variance of a given population, it is necessary to first calculate the mean of the scores, then measure the amount that each score deviates from the mean and then square that deviation (by multiplying it by itself). Learn the logic behind fundamental statistical concepts!

To obtain the variance start by subtracting the average from each data item. Since there will be about as many items above average as below average, the resulting list of numbers will have about as many positive values as negative values.
