Standard deviation is a useful measure of spread fornormal distributions. In normal distributions, data is symmetrically distributed with no skew. Most values cluster around a central region, with values tapering off as they go further away from the center. The standard deviation tells you how spread out from … See more

OverviewInterpretation and applicationBasic examplesDefinition of population valuesEstimationRelationship between standard deviation and meanRapid calculation methodsHistoryA large standard deviation indicates that the data points can spread far from the mean and a small standard deviation indicates that they are clustered closely around the mean. For example, each of the three populations {0, 0, 14, 14}, {0, 6, 8, 14} and {6, 6, 8, 8} has a mean of 7. Their standard deviations are 7, 5, and 1, respectively. …
