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

OverviewBasic examplesDefinition of population valuesEstimationInterpretation and applicationRelationship between standard deviation and meanRapid calculation methodsHistoryIn statistics, the standard deviation is a measure of the amount of variation of a random variable expected about its mean. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. The standard deviation is commonly used in the determin…
