The rationale in research is the justification or reasoning behind conducting a particular study. It explains why the research is necessary, what knowledge gap or problem it aims to address, and why the topic is significant. Essentially, the rationale answers the question "why this research?" by setting the context and demonstrating the study's importance and relevance to the field or society

. Key elements of a research rationale include:

• Background : Summarizes existing research and identifies gaps or unresolved issues.
• Problem Statement : Clearly defines the specific problem or gap the research will address.
• Justification and Relevance : Explains why addressing this problem matters and the potential impact of the research.
• Research Objectives and Methodology : States what the study aims to achieve and how it will approach the investigation

A well-written rationale helps convince readers, reviewers, or funding bodies of the study's novelty, significance, and the researcher's expertise. It also guides the research process by clarifying the focus and scope of the study

. In summary, the rationale is the foundation of a research project that justifies its purpose, significance, and approach, ensuring the research is meaningful and contributes to advancing knowledge
