Therefore, the standard deviation is 2. In this case 100% of the values in the population are at one standard deviation of the mean. The standard deviation is the most common measure of statistical dispersion, measuring how widely spread the values in a data set are. If the data points are close to the mean, then the standard deviation is small.

Calculating the Standard Deviation. If x is a number, then the difference "x - mean" is called its deviation. In a data set, there are as many deviations as there are items in the data set. The deviations are used to calculate the standard deviation. If the numbers belong to a population, in symbols a deviation is x − μ .

Add two more data values, one above and one below the mean, which will increase the standard deviation. Calculate the new standard deviation. Problem 2. A z-score indicates the location of a data value relative to the mean in terms of standard deviation units. You are given a data set with a mean of µ = 10 and a standard deviation of σ = 2.
