The easiest way to collect data is by using charts or graphs as shown below

We can find the required data by looking at the above graph.

**1) Question: **How many pets were owned by the same number of boys and girls?

** Answer: **4 pets.

You will note that the height of the bar is the same for both boys and girls for 4 pets.

**2) Question: **How many more girls than boys were part of the survey?

** Answer: **2 girls.

Therefore, in total, the number of girls versus boys = total for girls : 1 + 5 + 7 + 0 + 1 = 14

total boys : 2 + 3 + 5 + 1 + 1 = 12
