How to determine scale
• Scale is determined by your highest & lowest number.
• In this case your scale would be from 2 – 22.

by your scale. • In this case your scale
would be from 2 – 22 and you want the scale to fit the graph.
• The best interval would be to go by 5’s.

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

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
