If the relationship is shown to be linear, correlations can be done to indicate the strength and direction of the relationship between the two variables in question. If the assumptions of Pearson's product moment correlation — a parametric test, are violated, there is a non-parametric equivalent which can be used instead.
Once it has been established that there is a linear relationship between the two variables in question, it is possible to discover how much one variable changes in relation to ...
