For the following population of N = 6 scores: 2, 9, 6, 8, 9, 8

a. Calculate the range and the standard deviation. (Use either definition for the range.)

b. Add 2 points to each score and compute the range and standard deviation again. Describe how adding a constant to each score influences measures of variability.
