Which research method is used to determine causality?

Question

Quizplus · Accepted Answer

Experimental research is the method used to determine causality because it involves the manipulation of an independent variable to see if it causes a change in a dependent variable. The experimental design allows for control over extraneous variables and random assignment of participants, which strengthens the ability to draw cause-and-effect conclusions. Correlative research can only establish a relationship between variables but cannot prove causality. Observational research and case studies cannot establish causality due to lack of manipulation of variables.
