(b) Use the defining formula to compute the sample standard deviation s. Recall the defining formula used to compute the sample standard deviation s = where x is a n – 1 member of the data set, x is the mean, and is number of data values. Before using the formula, we must determine x and n. There are five values in the data set 1, 6, 7, 8, 9, so n = Calculate the mean x = L* by taking the average of the data values, which is dividing the sum of the data in values by the number of data values.
