In order to use the defining formula for sample standard deviation, it is helpful to first calculate (x – x)² for each data value in the data set 1, 6, 7, 8, 9. Use the values in the data set and the previously determined mean, x = 6.2, to complete the following table. 8 6.2 6.2 6.2 6.2 6.2 х— х -5.2 0.8 2.8 (x – x)² 27.04 0.04 3.24
