4.9. Look at distributions a and b. Just by looking at the data, decide which one has the larger standard deviation and estimate its size. Finally, make a choice between the deviation-score and the raw-score formulas and compute S for each distribution. Compare your computation with your estimate. (LOs: 5, 7)

a. 5, 4, 3, 2, 1, 0

b. 5, 5, 5, 0, 0, 0
