Then I did the distance between each of those points and the mean. So I just took, let's say, 0 minus 5. This is this distance. So this just tells you the point minus 20 is 25 less than the mean, right? That's all I did there. Then I divided that by the standard deviation, and this is the z-score, the standard z-score. So this tells me how many standard deviations is minus 20 away from the mean.
