When we compare two different variables we usually create scatter plots to help us see if there is a relationship between the data.
In class we examined the scatter plots below:
Each scatter plot represented a different relationship that we have already studied:
Scatter Plot 1: Linearly Decreasing
Scatter Plot 2: Exponential Decay
Scatter Plot 3: No Relationship
Scatter Plot 4: Quadratically Increasing
For a scatter plot to show some sort of relationship the points do not have to form a perfect relationship. They just have to be close.
