What does rationale of research mean?

The rationale of research refers to the underlying reasons and justifications for conducting a particular study. It outlines the significance of the research question, the gaps in existing knowledge, and the potential contributions the study may make to the field. Essentially, it helps to clarify why the research is necessary and how it can advance understanding or address specific problems. A well-defined rationale strengthens the overall research proposal and provides a clear context for the investigation.
