Multimethod research involves using multiple research methods, such as surveys, interviews, observations, and experiments, to study a particular phenomenon or research question. This approach allows researchers to gather a more comprehensive and rich set of data, and can help validate findings by comparing results across different methods. Multimethod research is commonly used in social sciences and psychology to provide a more holistic understanding of complex behaviors and phenomena. By integrating multiple methods, researchers can overcome the limitations of one method and enhance the overall validity and reliability of their findings.
