Which type of graph(s) would be most appropriate for displaying

the data that would be collected to answer each question?

1.Which of the five books read in English class this year is the one the

students liked best?

2.Does the number of customers in a store vary at different times of the day?

3.What is the cost of an adult movie ticket at several different theaters?

4.Discuss and Write Consider the problem at the beginning

of the lesson. Suppose that there are 25 students in Manuel’s

math class and Manuel surveys 20 of them. Would it still be

appropriate to use a circle graph to display the results?

Why or why not?

Each year for the past 5 years, Manuel’s teacher has asked a student to

survey the students in the math class about their favorite sport. The chart

below shows the data that the teacher recorded about baseball as the

favorite sport. What kind of graph would be appropriate for displaying

how the percent of students choosing baseball changed over the past

5 years? Create an appropriate graph to display the data.

Since the graph will show a change over time, a line graph would

be the most appropriate way to display the data.
