Miriam took a survey, asking each family in her neighborhood how many pets they have. She made a graph showing the results:
What is the median number of pets per family?
0, 0, 0, 0, 0, 0, 1, 1, 1, 2, 2, 2, 3, 3, 3, 3, 3, 3, 4, 5
There are 19 numbers in total, and the middle two numbers are both 2, therefore the median is 2.
