Research is a systematic investigation aimed at discovering, interpreting, or revising facts, events, behaviors, or theories. It involves the collection, analysis, and interpretation of data to answer questions or solve problems. Research can be conducted in various fields, including science, social sciences, humanities, and applied professions, and often follows a structured methodology. It typically encompasses both quantitative approaches, which involve numerical data and statistical analysis, and qualitative approaches, which focus on understanding concepts, experiences, or social phenomena. The ultimate goal of research is to contribute to a body of knowledge, test hypotheses, inform practice, and guide decision-making.
