This document discusses research, including defining what research is, the key components of a research study, how to identify a research problem and gap, and how to eliminate a research gap. It notes that research involves searching again for new facts or modifying older ones. A well-defined research problem and hypothesis are essential, as are scientific techniques and logical interpretation of results. Identifying reasons for a research gap and characterizing it using a PICOS framework can help eliminate gaps. The document also discusses the importance of research ethics in promoting integrity and protecting human subjects.
