Two data points can have the same score if they are the same distance from the mean of the data set. For example, if the mean is 10, 8 and 12 will have the same z score.
OpenStudy (anonymous):
Gotcha, I thought it was false too but I read somewhere that every z score is unique or something
OpenStudy (anonymous):
It's unique for any x in the data, but a particular number x(p) may appear more than once in the data, and they will have the same unique z score.
