Coherence in research refers to the logical and consistent connection between different ideas, concepts, and findings within a study. It indicates how well all parts of a research work together to form a cohesive and unified argument or narrative. In research, coherence is important for ensuring that the study is clear, understandable, and persuasive to the reader. This may involve organizing information in a logical manner, maintaining consistency in language and terminology, and making sure that all parts of the study support the main research question or hypothesis. Ultimately, coherence helps to enhance the quality and effectiveness of research by helping to create a strong and convincing argument.
