Quizplus · Accepted Answer

Both correlational study and differential research design aim to examine the relationship between two variables. In a correlational study, researchers observe the relationship between two variables without manipulating them, while in a differential research design, researchers manipulate one variable to see how it affects another variable. Both approaches aim to establish a link between two variables.
