Students measure their heights, arm lengths, and stride lengths to determine whether there is a relationship among the values. Which type of graph should the students use to display their data?

A scatter plot displays paired numerical measurements, such as each student's height and arm length, as points. The pattern of points can show whether the measurements are related. A bar graph and histogram show distributions or categories, while a line graph is typically used to show change over an ordered sequence such as time.
