Association. As noted in the previous page, researchers are usually interested in relationships between variables. When two variables are related, we say that there is association between them.. For example, consider the height, X, and weight, Y, of a sample of school children.Tall children tend to be heavier, so high values of X are associated with high values of Y. To understand the difference between correlation and causation, let’s start with the definitions. Correlation indicates a relationship between two variables, usually found in statistics. The most common form or correlation is Pearson’s product moment, which produces a coefficient “r” that describes the strength and direction of a linear
