What does the concept of triangulation refer to in research methods?

Triangulation in research methods refers to the use of multiple methods or approaches to gather data and answer research questions. This technique enhances the validity and reliability of findings by providing a more comprehensive perspective. By employing different methods, researchers can cross-verify results, gain deeper insights, and account for potential biases that might occur when relying on a single method. For example, a study might combine qualitative interviews with quantitative surveys to explore a phenomenon from both statistical and narrative angles, ultimately leading to a richer understanding of the subject matter. Thus, the correct answer emphasizes the importance of using various methods to enhance clarity and robustness in research.
