Quizplus · Accepted Answer

The main difference between an experiment and a correlational study is that an experiment involves the manipulation of variables, while a correlational study does not. In an experiment, researchers manipulate an independent variable and observe the effects on a dependent variable, while in a correlational study, researchers observe the relationship between two variables without manipulating them. Therefore, choice D is the correct answer.
