What is Sample Standard Deviation

The standard deviation of the sample is a measure of how widely the values in the sample are scattered relative to their average. By definition, the standard deviation is equal to the square root of the variance: The standard deviation does not take into account the magnitude of the values in the sample, but only the degree to which the values are scattered around their mean.
