Hi

There seems to be an increase in Standard Deviation (SD) questions in the quant. After few workouts and some assistance from the Quant studs in this club, i got over with the Probability, Combination stuff.

Now, comes this SD stuff. I have not seen even a single SD question. What kind of a SD question does not encounter in the GMAT. Can anyone give an example. And also let me know where can I find the study material.

Guys I have my test on the 22of July.
Thanks Bros

Thanks Emman

Could you provide me with an example question on the SD, similar to what GMAT test (so that I can get a gist, a overall idea) to what limit does this go. This will help me make a decision on 'Should I eliminate studying for the SD' and concentrate on other stuff.

1. There are 2 sets:

A = {100, 101, 102, 103, 104, 105, 106}

B = {97, 99, 101, 103, 105, 107, 109}

Standard deviation is larger for

A. set A

B. set B

C. they are equal

D. etc. etc.

2. Range of the set = 0. What is the standard deviation of this same set?

3. S.d. of the set = 0. What is the range of this same set?
