Correlational research can provide information about relationships between variables. For example, is unemployment associated with depression? Is having children associated with increased life satisfaction? Is exercise associated with happiness? In addition to providing information about whether or not two variables are correlated, correlations can inform about the direction of the association and the strength of the relationship.
- What two variables were being tested for a correlation?
- How were these variables operationally defined?
- What correlation coefficient was found? What does the number (coefficient) mean?
- How can this correlation be interpreted? How could it be misinterpreted?
