Research is a systematic and methodical investigation aimed at discovering, interpreting, and revising knowledge about a specific topic or phenomenon. It involves the collection, analysis, and interpretation of data to answer questions, solve problems, or contribute to existing understanding in a particular field. Research can be qualitative, quantitative, or a mix of both, depending on the nature of the inquiry. It is guided by a clear purpose, structured methodology, and ethical considerations to ensure validity and reliability. Ultimately, research drives innovation, informs decision-making, and advances human understanding across various disciplines.
