Which of the following sets of ordered data has the largest

Which of the following sets of (ordered) data has the largest standard deviation?


Set A: 57, 60, 60, 60, 60, 60, 60, 63
Set B: 57, 58, 59, 60, 61, 62, 63,64

Select one:

A. There is no way to tell without using a calculator/computer

B. Set B

C. Set A

Solution

SET B having gretest standard deviation.

Standard Deviation is the value deviated from mean.

By looking the data we can conclude SET A having mean 60.

But SET B having different mean and the values in SETB also not equally distributed as SETA.

So answer is SETB
