Calculating standard deviation and variance using the definitional formula Consider a data set containing the following values: 92 84 85 93 95 89 86 91 The mean of the preceding values is 89.375. The deviations from the mean have been calculated as follows: 2.625 -5.375 -4.375 3.625 5.625 -0.375 -3.375 1.625 If this is sample data, the sample variance is and the sample standard deviation is .If this is population data, the population variance is and the population standard deviation is .Suppose the smallest value of 84 in the data was misrecorded as 85, If you were to recalculate the variance and standard deviation with the 85 instead of the 84, your new values for the variance and standard deviation would be.
