Experimental research is a scientific approach used to investigate the cause-and-effect relationships between variables. It is often used in fields such as psychology, biology, and the physical sciences to test hypotheses and draw conclusions about how changes in one variable may influence another. Experimental Research can take various forms, including laboratory experiments, field experiments, and natural experiments, depending on the research setting and the level of control required. The key to effective experimental research is the systematic manipulation of variables while maintaining rigorous controls to minimize bias and confounding factors.
