Which set of data would have the highest standard deviation?
A
1, 2, 3, 4, 5, 6
B
23, 23, 25, 26, 27, 32
C
1, 5, 10, 15, 20, 25
D
50, 51, 56, 58, 59, 62
Explanation: 

Detailed explanation-1: -Answer: s = 15.1383 & 14.3614 for sample & total population respectively for the dataset 5, 10, 15, 20, 25, 30, 35, 40, 45 and 50.

Detailed explanation-2: -Which data set has the greatest sample standard deviation? The data set that has more entries that are farther away from the mean.

Detailed explanation-3: -If you have 100 items in a data set and the standard deviation is 20, there is a relatively large spread of values away from the mean. If you have 1, 000 items in a data set then a standard deviation of 20 is much less significant.

Detailed explanation-4: -The higher the CV, the higher the standard deviation relative to the mean. In general, a CV value greater than 1 is often considered high.
