Regression analysis is a statistical technique that is very useful for these types of problems 8 ∑ ∑ ∑ = = = − × − − − = n i i n i i n i i i x x y y x x y y 1 2 1 2 1 ( ) ( ) ( )( ) ρˆ −1≤ ρˆ ≤1

A scatterplot is a type of data display that shows the relationship between two numerical variables. Each member of the dataset gets plotted as a point whose coordinates relates to its values for the two variables. For example, here is a scatterplot that shows the shoe sizes and quiz scores for students in a class: Created with Raphaël.

The correlation only measures the strength of a linear relationship between two variables. It ignores any other type of relationship, no matter how strong it is. For example, consider the relationship between the average fuel usage of driving a fixed distance in a car, and the speed at which the car drives:
