What is 'Standard Deviation'. Standard deviation is a measure of the dispersion of a set of data from its mean. If the data points are further from the mean, there is higher deviation within the data set. Standard deviation is calculated as the square root of variance by determining the variation between each data point relative to the mean.
Standard Deviation Calculator. Standard Deviation (SD) is the measure of spread of the numbers in a set of data from its mean value. It is also called as SD and is represented using the symbol Ï (sigma). This can also be said as a measure of variability or volatility in the given set of data.
