The -score of a measurement gives the number of standard deviations between that measurement and the mean of the dataset.
For example, for this dataset, it is given that whereas . For a -year-old viewer, .
How far away is this observation from the mean of this population? .
The -score of this observation would be the approximate number of standard deviations that corresponds to this difference:
.
Similarly:
For , .
Separately adding and subtracting from would give the upper bound and the lower bound of the age range within standard deviation from the mean:
Similarly, for the interval within standard deviations from the mean:
For the interval within standard deviations from the mean:
