Both correlational studies and differential research designs involve identifying and demonstrating the existence of a relationship between two variables. Correlational studies measure the degree of association between two variables, while differential research designs compare groups based on a variable of interest to identify any differences in outcomes or behavior. However, they differ in that correlational studies do not manipulate any variables, while differential research designs typically involve some level of manipulation or control over the variable of interest.
