Correlational study is used to show the type of association or relationship which exists between two or more variables using statistical analysis. Ken's research shows that <em>there</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>relationship</em><em> </em><em>between</em><em> </em><em>childhood</em><em> </em><em>anger</em><em> </em><em>management</em><em> </em><em>and</em><em> </em><em>adult</em><em> </em><em>earning</em><em>.</em><em> </em>
