The following sets each have a mean of 8 and the standard deviations are given in variable form.
The following sets each have a mean of 8 and the standard deviations are given in variable form.
Set I = {8, 8, 8, 8, 8, 8}, standard deviation = A
Set II = {2, 2, 2, 14, 14, 14}, standard deviation = B
Set III = {5, 6, 7, 9, 10, 11}, standard deviation = C
Rank these three standard deviations from least to greatest.
Answer/Solution
A, C, B
Steps/Work
The answer should be E as the mean is least deviated in Set I followed by Set III and then Set II.
