The following sets each have a mean of 20 and the standard deviations are given in variable form.
Set I = {10, 10, 10, 30, 30, 30}, standard deviation = P
Set II = {14, 16, 18, 22, 24, 26}, standard deviation = Q
Set III = {20, 20, 20, 20, 20, 20}, standard deviation = R
Rank these three standard deviations from greatest to least.
Answers.
A) R, P, Q
B) P, Q, R
C) R, Q, P
D) Q, R, P
E) Q, P, R
The answer should be P, Q, R as the mean is most deviated in Set I followed by Set II and then Set III.
