Literature-based research involves reviewing existing written works, such as books, articles, and reports, to gather information on a specific topic. This method helps researchers understand what has already been studied and identifies gaps in knowledge. It is commonly used in fields like social sciences, healthcare, and education. In this type of research, scholars analyze and synthesize findings from various sources to draw conclusions or develop new theories. By relying on established literature, researchers can build on previous work and ensure their studies are grounded in existing knowledge, making their contributions more relevant and impactful.
