You want to find out if there is a relationship between two variables, but you don’t expect to find a causal relationship between them. Correlational research is a type of non-experimental research in which the researcher measures two variables and assesses the statistical relationship (i.e., the correlation) between them with little or no effort to control extraneous variables. Correlational research studies are one common type of scientific research, and one type of quantitative research. It is important to have a good understanding of correlational research.

However, not having a relationship does mean that one variable did not cause the other.) There is a strong relationship between the number of ice cream cones sold and the number of people who drown each month. However, correlational studies lack the components of random control trials and quasi-experimental studies to allow them to assign causality. A correlational study might look at diferences in behaviors or outcomes, but it cannot prove that a specifc factor caused the changes. Correlational studies are used to show the relationship between two variables. Unlike experimental studies, however, correlational studies can only show that two variables are related—they cannot determine causation (which variable causes a change in the other).
