When to use… Bar graphs Line 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

Practice Interpreting Data: It is important that you be able to interpret data that is represented in graph form.
