When the standard deviation is large, the scores are more widely spread out on average from the mean. The standard deviation is calculated to find the average distance from the mean. Practice Problem #1: Calculate the standard deviation of the following test data by hand. Use the chart below to record the steps.

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. As well, if many data points are far from the mean, then the standard deviation is large.

Familiar Examples: • The sample mean: • The sample variance: • The sample standard deviation: • These are point estimates (single numbers). • An interval estimate (confidence interval) is an interval of numbers that is designed to contain the parameter value.

When the examples are spread apart and the bell curve is relatively flat, that tells you that you have a relatively large standard deviation. One standard deviation away from the mean in either direction on the horizontal axis (the red area on the above graph) accounts for somewhere around 68 percent of the people in this group.
