Standard Deviation---Confused

by vishugogo » Mon Oct 07, 2013 8:48 pm
If sets A and B have the same number of terms, is the standard deviation of set A greater than the standard deviation of set B?

1) The range of set A is greater than the range of set B.

2) Sets A and B are both evenly spaced sets.

OA C
