In terms of the mean and standard deviation:
Comment: A z-score is a measuring device. It is the number of standar
deviation some particular raw score is above or below the mean.
The mean has a z-score of zero.
-----------------------------------------
- What does it mean to say that a particular value of x has a standard score of +1.2?
x is 1.2 standard deviations to the right (above) of the mean.
-----------------------------------
- What does it mean to say that a particular value of x has a z-score of -2.1?
x is 2.1 standard deviations to the left (below) of the mean.
