Organizing raw data can help you see patterns and trends. One way to organize data is using a line plot.
A line plot uses a number line to show how often a value occurs in a data set.

1. Find the least value, 0, and the greater value, 10 in the data set.
2. Draw a number line from 0 - 10.
3. Place an 'x' above each number on the number line for each time it appears in the data set.
 x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x <-- -- -- -- -- -- -- -- -- -- --> 0 1 2 3 4 5 6 7 8 9 10
