Descriptive research methods are nonexperimental methods that are used to acquire information about a phenomenon or to describe the relationship between two or more phenomena. Nonexperimental methods are different from experimental methods in that they do not involve the manipulation of variables or the modification of the situation under investigation. Explain the purpose of correlational research and develop three research examples of when a correlational study would be required. Pertaining to the examples you provided, what type of information would the data/results provide and what would the proposed strength of the associations be? Discuss some potential third variables that could be responsible for the relationships between the variables and how those could be threats to internal validity.
