The hourly salaries of the workers at a restaurant are shown below.

$7.75, $8.50, $7.25, $9.00, $30.00, $8.25, $7.75, $9.00

• The outlier is $7.25 which causes the median to be a better representation of typical salary than the mean.

• The outlier is $30.00 which causes the mean to be a better representation of the typical salary than the median.

• The outlier is $30.00 which causes the median to be a better representation of the typical salary than the mean.
