This shows two horizontal lines. Both lines are marked and labelled with a scale in one unit intervals from 47 to 71. The top line is labelled ‘Heights of sunflowers of variety A (incches).’ Dots are plotted on the line at 55, 58, 59, 60, 62, 65, and 66. A second dot is plotted immediately above the dot at 55, to indicate that two sunflowers had a height of 55 in. The second line is marked and labelled with a scale in one unit intervals from 47 to 71. The line is labelled ‘Heights of sunflowers of variety B (inches).’ Dots are plotted on the line at 50, 52, 54, 60, 61, 67, and 69. A second dot is plotted immediately above the dot at 67.
