# Lesson Worksheet: Appropriate Data Display Mathematics

In this worksheet, we will practice selecting appropriate diagrams to display data.

**Q3: **

Students in Hannah's class can speak English, French, Spanish, or a collection of all three. She asks each person to list which of the three languages they speak. She wants to analyze how many people in her class speak one language and how many speak more. Which of the following would be the best choice to display the data that she collects?

- AVenn diagram
- BBar graph
- CLine plot

**Q4: **

The following graphs all display data about the pets owned by the students in a class.

Which of these displays should we use if we want to analyze the most common type of pet?

- AThe Venn diagram
- BThe bar graph

Which of these displays should we use if we want to compare the number of students who own exactly one pet?

- AThe bar graph
- BThe Venn diagram
