When 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.
For example, if one variable tends to increase at the same time that another variable increases, we would say there is a positive relationship between the two variables. If one variable tends to decrease as another variable increases, we would say that there is a negative relationship between the two variables.
