Describe how a researcher might use a descriptive method (case study, naturalistic observation or a survey) to answer this question
Next, describe how a researcher might use the correlational method to study this question
Finally, describe how you could conduct an experiment to study the question you chose. In your experiment, be sure to specify what the independent and dependent variable are. Include enough detail that a person could take your description of the study and actually conduct it.
Explain which of these three methods can determine causality.
