Question 360765
Recall that the z score is {{{z=(x-mu)/(sigma)}}}. The units for both x and {{{mu}}} are in centimeters. So the units for {{{x-mu}}} are in centimeters. Also, the units for {{{sigma}}} are in centimeters. So the units will cancel for {{{(x-mu)/(sigma)}}}



This means that the z-score has no units.
