Given the following set of data, demonstrate that adding a constant to, or subtracting a constant from, each score does not change the standard deviation. (What happens to the mean when a constant is added or subtracted?) [5 4 2 3 4 9 5].

Given the data in Exercise 2.44, show that multiplying or dividing by a constant multiplies or divides the standard deviation by that constant. How is this related to what happens to the mean under similar conditions?
