IntroductionThe 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 stand...

= population meann = number of scores in sample. Is there an easy way to calculate the standard deviation? Yes, we have a sample and population standard deviation calculator that shows you all the working as well! Currently, our calculator is under maintenance, but if you would like us to let you k...
