If M is a negative integer and Q is a positive integer, which of the following could be the standard deviation of a set {-7, -5, -3, M, 0, 1, 3, Q, 7}?
I. -1.5
II. -2
III. 0  Choose one:
A) I only	B) II only	C) III only	D) I and III only	E) None
If M is a negative integer and Q is a positive integer,The answer should be (E) as S.D cannot be negative. It is only 0 if all numbers in the set are equal, which is not the case either=None
<result>E</result>
