Question

Quizplus · Accepted Answer

Experimental research is the best way to identify a causal relationship between two variables because it involves manipulating an independent variable to see its effect on a dependent variable while controlling for other possible factors (through random assignment or matching). This allows researchers to establish cause-and-effect relationships and rule out alternative explanations for the results. Observational and archival research cannot establish causality, while correlational research only identifies the strength and direction of the relationship between variables, but not causality.
