Example Two

The data below are the yearly wages (in dollars) of ten people working at an on-line music store.


DATA: { 41 000, 41 000, 41 000, 41 000, 43 000, 45 000, 48 000, 50 000, 50 000, 250 000 }


Mean: 65 000

Median: 44 000

Mode: 41 000


Given the way the data is distributed in this example (with one persons yearly wage being so large), the median is probably the best measure of central tendency.

NOTE: Nine people are below the mean and one person is above the mean, so the mean is probably not the most appropriate measure of central tendency.

NOTE: The majority of people working at the store (four in this case) are new employees who earn "starting wages". The mode, therefore, is probably not the most appropriate measure of central tendency.


The median yearly wage of ten people working at an on-line music store is $44 000.00.
