In simple short English give me notes on all there's to know on research methods for my exams tomorrow

There are two main types: qualitative research explores ideas and experiences, often through interviews or observations. Quantitative research uses numbers and statistics to test hypotheses, usually with surveys or experiments.

Common tools include surveys (questionnaires), interviews (talking to people), and observations (watching behavior). Researchers often study a small group, called a sample, to learn about a larger population. It is important to conduct all research ethically, protecting participants' privacy and well-being.
