OverviewBasic examplesDefinition of population valuesEstimationInterpretation and applicationRelationship between standard deviation and meanRapid calculation methodsHistorySuppose that the entire population of interest is eight students in a particular class. For a finite set of numbers, the population standard deviation is found by taking the square root of the average of the squared deviations of the values subtracted from their average value. The marks of a class of eight students (that is, a statistical population) are the following eight values: These eight data points have the mean (average) of 5:
