Data

Find the mean

Process

1.- Sum up all the earthquakes

    11 + 23 + 16 + 15 + 25 + 22 + 20 + 16 + 23 + 18 = 189

2.- Divide the total number of earthquakes by the  numbers of years.

Total number of years = 10

            189/10 = 18.9

3.- Round to the nearest tenth

            18.9 ≈ 19

22 and 22
