How can nonexperimental research in psychology add to what we already know by common sense?
***Nonexperimental research involves observing and measuring things
as they are. Naturalistic observation, interview, survey, case
history, and psychometric scales are some of the methods used
when it is not possible or unethical to manipulate an independent
variable. Nonexperimental research is used to provide solutions
to problems. Nonexperimental research can add to what we know
by common sense because we can test our beliefs to see how true
they are.***
Duke University in Durham, North Carolina gives a brief description of research methods in psychological science.
Professor William N. Singleton from Bridgewater State College lists the “Criteria for Establishing Causality in Nonexperimental Situations” by discussing the X -Y relationship.
