20 famlies were surveyed

1. We can use a weights to find the average

[ 6(0) + 3(1) + 3(2) + 6(3) + 1(4) + 1(5)] / 20 =

[ 36 ] / 20 =

18/10 =

1.8 pets = average

2. List the data

0, 0, 0, 0 ,0, 0, 1, 1, 1, 2, 2, 2, 3, 3, 3, 3, 3, 3, 4, 5

The median is the sum of the 10th and 11th values / 2 = [ 2 + 2 ] / 2 = 4/2 = 2
