L = {3, 4, 5, 5, 6, 7}
M = {2, 2, 2, 8, 8, 8}
N = {15, 15, 15, 15, 15, 15}
Rank those three sets from least standard D eviation to greatest standard deviation.	Choose the correct choice from the following answers.
A) L, M, N	B) M, L, N	C) M, N, L	D) RANKING=N, L, M	E) N, M,
Square of Standard deviation is sum of squares of deviation from the mean divided by the number of terms.   If deviation from the mean is higher for the same number of elements, standard deviation will be higher.   L = {3, 4, 5, 5, 6, 7}   Mean is 5 and deviation of 2 elements from mean is 0, of 2 elements is 1 and of 2 elements is 2.   M = {2, 2, 2, 8, 8, 8}   Mean is 5 and deviation of all elements from the mean is 3. So SD here will be higher than SD of L.   N = {15, 15, 15, 15, 15, 15}   Mean is 15 here and all elements have 0 deviation from mean so SD = 0 here. This is the minimum possible SD.   Answer N, L, M   Answer (RANKING=N, L, M)
<result>D</result>
L = {3, 4, 5, 5, 6, 7}
M = {2, 2, 2, 8, 8, 8}
N = {15, 15, 15, 15, 15, 15}
Rank those three sets from least standard D eviation to greatest standard deviation.
