Info on a scatter diagram:
The Scatter Diagram shows how the values of two variables relate to one another. Is there a relationship and can one variable be used to predict another variable? For example, is there a relationship between the amount of fertilizer that you use and the how tall a plant grows? Or is there a relationship between how tall a man grows to be and how tall his father grew to be? Does the height of the father predict the height of the son?
