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, the researcher deliberately changes one variable (independent variable) to observe its effect on another variable (dependent variable). In a correlational study, the researcher simply measures the relationship between variables without manipulating them. Therefore, option C is the correct answer.
