Write a research question for a correlational study and identify the specific statistical test(s) appropriate for data analysis. If a researcher is looking for “differences” between groups or before and after treatments, what type of analysis would be performed? Write a research question for this type of study and identify the specific statistical test(s) appropriate data analysis. Be sure to cite your references.
