Standard deviation and variance of a sample and a population Consider a data set containing the following values: 80 94 93 106 91 9O 96 99 The mean of the preceding values is 93.625. The deviations from the mean have been calculated as follows: 13.625 0.375 O.625 12.375 2.625 3.625 2.375 5.375 If this is sample data, the sample variance is V and the sample standard deviation is V . If this is population data, the population variance is V and the population standard deviation is V Suppose the smallest value of 80 in the data was misrecorded as 88. If you were to recalculate the variance and standard deviation with the 88 instead of the 80, your new values for the variance and standard deviation would be V . 6.
