Find the mean and median for this set of number: 80, 70, 60, 40, 80.

Median: 70 mean: 55.

40, 60, 70, 80, 80

Mean = 66

Median = 70

(The mean of a set of numbers is the average so add all the numbers up and divide by the number of numbers = 40+60+70+80+80 = 330/5 = 66)

(The median of a set of numbers is the middle number = 70)
