1. Graphing Vocabulary Terms
Direct Relationship
If one variable increases then the other variable increases (or if one decreases the other decreases)
Ex:
Temperature (o C)
Depth Below Surface (km)

2. Inverse (indirect) Relationship
As one variable increases the other variable decreases (or vice versa)
Ex:
Elevation (km)
Temperature (o C)

3. Cyclic Relationship Reoccurring or up and down Ex: Temperature (o C)
Years

4. Extrapolate Extending the trend of the graph to make a prediction Ex:
Temperature (o C)
Years

5. Correlation a relationship between two (or more) variables
Ex: There is a strong correlation a planets distance from the Sun and its temperature.
