We want to calculate the z -scores.
00:01
We have a mean of 100 and we have a standard deviation of 16.
00:07
And we have the scores 112, 109, 56, 88, 135, and 99.
00:17
We're going to do all of these the same way.
00:19
Our z -score is going to be the data point minus the mean over the standard deviation.
00:25
In each one of these, we have a data point.
00:28
So my z -score is going to be 112 minus 100 over 16.
00:33
112 minus 109 over 16.
00:37
112 minus 56 over 16...
