Choose a scale that lets you make the graph as large as possible for your paper and data

The amount of space between one number and the next or one type of data and the next on the graph.

The interval is just as important as the scale

When to use…

• Bar graphs– Used to show data that are not continuous.– Allows us to compare data like amounts or

frequency or categories– Allow us to make generalizations about the data– Help us see differences in data

• Line Graphs– For continuous data– useful for showing trends over time
