Ms. Li gave her students a quiz that was supposed to take 6 minutes to complete. She asked her students to record the amount of time, to the nearest minute, that it took them to
complete the quiz. Ms. Li wants to create a data display that will summarize the data and
show how many students took 6 minutes to complete the quiz. Which data display should
she create?
a box plot
a histogram with intervals 1-4,5-8, and 9-12
a dot plot
a histogram with intervals 1-3, 4-6, 7-9, and
10-12
