Quizplus · Accepted Answer

The range of Z scores is always from -3 to +3. This is because a Z score represents the number of standard deviations away from the mean, and any score more than 3 standard deviations away from the mean is considered extremely unlikely. Thus, the correct range of Z scores is +3 to -3.
