Explain your answer. SS = --(X - )2. When you square a real number, the result is always non-negative. ... The only way that each squared deviation score can be equal to 0 is if all of the scores equal the mean. Thus, when the standard deviation equals 0, all the scores are identical and equal to the mean.
