Explain the difference between a correlational and an experimental research study. Be sure to explain what type of conclusions can be drawn from each
What will be an ideal response?
Experimental research involves the manipulation of an independent variable to determine its effect on a dependent variable. Experimental research is a good research method for determination of cause-and-effect conclusions.
Correlational methods allow researchers to explore research questions that cannot be examined with experimental procedures. However, they do not involve manipulation and thus cannot lead to determination of cause and effect.
