? Question 7 10 out of 10 points
z scores allow comparison of variables that are measured on different scales.
? Question 8 10 out of 10 points
If the original raw score distribution is not normally distributed, the mean of the z transformation scores of the raw data will not equal 0.
? Question 9 10 out of 10 points
