Mean, Mode, Median

Average

Three types of averages are the mean, mode and median. The weekly salaries of six employees at McDonalds are $140, $220, $90, $180, $140, $200. For these six salaries, find: (a) the mean (b) the median (c) the mode.
 
List the data in order: 90, 140, 140, 180, 200, 220

                                                                               
Mean:    90+ 140+ 140+ 180 + 200 + 220 = 161.66666666
                                        6                             

Median:    90,140,140,180,200,220
The two numbers that fall in the middle need to be
averaged.     140 + 180 = 160
                           2 

Mode:   The number that appears the most is 140
