Population vs. Sample Variance and Standard Deviation When calculating variance and standard deviation, it is important to know whether we are calculating them for the whole population using all the data, or we are calculation them using only a sample of data. Standard Deviation vs Mean Standard Deviation. Standard deviation and Mean both the term used in statistics. Standard deviation is statistics that basically measure the distance from the mean, and calculated as the square root of variance by determination between each data point relative to mean.

However, the standard deviation is a measure of volatility and can be used as a risk measure for an investment. Assets with higher prices have a higher SD than assets with lower prices. If $x_1, x_2, \ldots, x_N$ denote $N$ values from a sample, however, then the (sample) standard deviation is $$s = \sqrt{\frac{1}{N-1} \sum_{i=1}^N (x_i - \bar{x})^2},$$ where $\bar{x}$ is вЂ¦
