Line Plots

3. 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.

4. 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

5. Test Scores
Make a line plot and identify any outliers, clusters and gaps. x x x x x x x x x x x x x x x x x x 78 80 82 84 86 88 90 92 94 96 98
