Our interest will be concerned with relationships between two variables which are not perfect.The 'Correlation' between x and y is r = 1.00 for the values of x and y on the left and r = -1.00 for the values of x and y on the right.hen we consider the relationship between two variables, there are three possibilities: 1  Both variables are categorical. 2  Both variables are quantitative. 3  One variable is categorical and the other is quantitative, for instance height and gender.
