Overview
The purpose of this lesson is to try and make students realize that they should not be intimidated by graphs. In economics we use graphs to do 3 simple things:
- Observe how something changes (variables)
- See if we can identify a pattern (relationship)
- Use that pattern to try and predict what will happen in the future
In this lesson, we cover all of the basic concepts of graphing to help students understand how graphs work.
