standard deviation. of a data set is the “average deviation from the mean.” σx – The lower case Greek letter σ is used to represent the standard deviation of a population data set. Sx – The lower case s is used to represent the standard deviation of a sample data set. Calculating standard deviation is a multi-step process.
