A psychologist conducts a research study and finds that children who are abused have more difficulty in school than children who are not abused
a. Is this an experimental, correlational, cross-sectional, or longitudinal study? Justify your choice.
b. Based on the study, the psychologist draws the conclusion that an abusive home life leads to poorer school performance in school. Is this conclusion justified? Why or why not?
What will be an ideal response?
Responses to the two parts of the question are as follows:
a. It is a correlational study because it investigates the extent to which two variables, abuse and school performance, are associated. (An experimental study looking at the possible effects of abuse would, of course, be unethical.)
b. The conclusion is not justified. Conclusions about cause-effect relationships cannot be drawn from correlational studies.
