if we have 2 sets with the same number of items in them. if both have equal standard deviations. will both groups be equal?
The quick answer: No, the 2 sets need not be equal.amyhussein wrote:if we have 2 sets with the same number of items in them. if both have equal standard deviations. will both groups be equal?
For example {1,2,3} and {7,8,9} have the same standard deviation, but the sets are not equal.
