- a. The responses for the question “What is your favorite beverage?” would be specific names. There is no range
in the data. Therefore a bar graph would be used. The beverage would be on thex−axis and the number of students
would be on they−axis. ABarGraph would be used.
b. The results would have to be grouped in intervals since each result represents a specific time. The time intervals
would be on thex−axis and the number of students would be on they−axis. AHistogram would be used.
c. Once again a histogram would be used since the results would have to be grouped in intervals since each result
represents a specific distance. The distance intervals would be on thex−axis and the number of people would be on
they−axis.
