Lesson 2-3 Line Plots

Line Plot One way to show how data are spread out is to use a line plot. A line plot is a diagram that shows the frequency of data on a number line. An “x” is placed above a number on a number line each time that data value occurs.

Line Plot You can make observations about the data from a line plot. Range: difference between the highest and the lowest number in the data. Cluster: data that appear to group together. x Gap: large space in data. x x x x x x x x x x x x x x x x x x x 2 4 6 8 10 12 14 16 18 20 Outliers are separated from the rest of the data
