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.
Regards
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?
