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 = 
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
