Consider a data set containing the following values: 60 93 84 80 95 99 78 90 The mean of the preceding values is 84.875. The deviations from the mean have been calculated as follows: –24.875 8.125 –0.875 –4.875 10.125 14.125 –6.875 5.125 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 60 in the data was misrecorded as 6. If you were to recalculate the variance and standard deviation with the 6 instead of the 60, your new values for the variance and standard deviation would be
