Standard deviation and variance are two key measures commonly used in the financial sector. Standard deviation of a data set is the square root of the calculated variance of a set of data. Variance is defined and calculated as the average squared deviation from the mean.

To calculate the variance, you first subtract the mean from each .

The formula for variance (s2) is the sum of the squared . The standard deviation is derived from variance and tells you, on average, how far each value lies from the mean . Thinking about how we can estimate the variance of a population by looking at the data in a sample. The formula for variance (s2) is the sum of the squared .
