Question

A group of 23 students participated in a math competition. Their scores are below:


Score (points) 20–29 30–39 40–49 50–59 60–69
Number of Students 4 7 5 4 3


Would a dot plot or a histogram best represent the data presented here? Why?
Histogram, because a large number of scores are reported as ranges
Histogram, because a small number of scores are reported individually
Dot plot, because a large number of scores are reported as ranges
Dot plot, because a small number of scores are reported individually
