      Standard deviation is a measure of the amount of variation or dispersion of a set of data values. A low standard deviation indicates that the data points tend to be close to the mean, while a high standard deviation indicates that the data points are spread out over a wider range. To calculate standard deviation, you need to know the mean of the data set and then find the square root of the average of the squared differences from the mean. Our calculator provides instant answers for you.
