Question

Suppose that 2 were subtracted from each of the values in a data set thatoriginally had a standard deviation of 5.5. What would be the standarddeviation of the resulting data?A. 7.5B. 5.5C. 3.5D. 2

Answer 1

Adding or subtracting a constant value (say the mean value of a variable) will not change its standard deviation.

- Thus, the answer is 5.5 (OPTION B)
