9. Lesson 8
I can represent measurement data with line plots.
Mrs. Byrne’s class is studying worms. They measure the lengths of the worms to the nearest quarter inch. The length of the shortest worm is 3¾ inches. The length of the longest worm is 5¾ inches. Kathleen says they will need 8 quarter-inch intervals to plot the lengths on a line plot. Is she right? Why or why not? 2

Mrs. Byrne’s class is studying worms. They measure the lengths of the worms to the nearest quarter inch. The length of the shortest worm is 3¾ inches. The length of the longest worm is 5½ inches. Kathleen says they will need 8 quarter-inch intervals to plot the lengths on a line plot. Is she right? Why or why not? 3¾ 4 4¼ 4½ 4¾ 5 5¼ 5½
No, Kathleen is not right. There are seven quarter-inch intervals from 3¾ to 5½, not eight.
