In other words, an independent variable is something that is chosen by the researcher to cause a change in another variable .

A correlation exists when a change in one variable coincides with a change in another variable . The fact that a correlation exists means that the two variables are associated statistically with one another. However, the mere fact that associations exist, does not necessarily mean that a change in one variable causes a change in another variable. Correlations are an indication that causality may be present. They do not necessarily indicate causation (Schaefer & Lamm, 1992: 38)....
