4. Measures of variability - Range, variance, standard deviation, and coefficient of Aa Aa =variation 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 largest value of 99 in the data was mlsrecorded as 96. If you were to recalculate the variance andstandard deviation with the 96 instead of the 99, your new values for the variance and standard deviation would be
