The standard deviation is a measure of the spread of scores within a set of data. Usually, we are interested in the standard deviation of a population.However, as we are often presented with data from a sample only, we can estimate the population standard deviation from a sample standard deviation. These two standard deviations-sample and population standard deviations-are calculated differently.In statistics, we are usually presented with having to calculate sample standard deviations, and so this is what this article will focus on, although the formula for a population standard deviation will also be shown.he standard deviation is a measure of the spread of scores within a set of data. Usually, we are interested in the standard deviation of a population.
