Imagine that you are asked to design a study that determines whether or not there is a relationship between self-esteem and happiness. The type of research design best suited to this task would be a correlational study.
A research design known as a correlational study examines the connections between two or more variables. Since correlational studies are not experiments, no variables are changed or under the experimenter's control. An association between two variables is referred to as a correlation.
Strong or weak, positive or negative correlations are possible. There may not always be a correlation. A correlation study may reveal a positive correlation, a negative correlation, or no association at all. The correlation coefficient is a numerical value that researchers can use to display the findings.
