What is the purpose of experimental methods in research?

The purpose of experimental methods in research is to alter conditions and observe outcomes. This approach allows researchers to establish cause-and-effect relationships by manipulating one or more variables while controlling others. By systematically changing certain conditions and observing the resulting changes in behavior or responses, researchers can gather evidence that supports or refutes hypotheses. This method is fundamental in experimental research because it provides a structured way to test theories under controlled conditions, enabling valid conclusions about how specific variables interact.

In experimental research, the manipulation of variables is crucial for determining if an observed effect is caused by the variable being adjusted or by other factors. This design leads to more reliable results and a deeper understanding of the phenomena being studied, distinguishing it from other research methods that may not provide the same level of clarity regarding causal relationships.
