Research methodology is the systematic process of collecting, analyzing, and interpreting data in order to answer a research question or test a hypothesis. It encompasses the overall approach and strategy that researchers use to conduct their studies, including the methods and techniques they employ to gather and analyze data. Research methodology involves various steps, such as defining the research problem, formulating a research design, selecting a sample, collecting data, analyzing and interpreting the data, and drawing conclusions. Different research methods can be used in this process, including quantitative methods (such as surveys, experiments, and statistical analysis) and qualitative methods (such as interviews, focus groups, and content analysis). Overall, research methodology is crucial in ensuring that research studies are conducted in a rigorous and systematic manner, leading to valid and reliable results that can contribute to the advancement of knowledge in a particular field.
