Question

Quizplus · Accepted Answer

Experiments are the only research method that involves manipulating an independent variable and controlling for constants in order to establish a cause-and-effect relationship. Focus groups and observational studies do not involve manipulating variables in this way, and projective techniques are a type of qualitative research method used for exploring attitudes and beliefs, but do not involve testing cause-and-effect relationships.
