Empirical analysis is a research method that involves the collection and analysis of data to test hypotheses and theories. This type of research relies on systematically gathered evidence, such as observations, experiments, surveys, or interviews, to draw conclusions about a particular phenomenon. Empirical analysis is commonly used in a variety of disciplines, including social sciences, natural sciences, and business, to provide objective and reliable findings that can inform decision-making and policy development. It is often considered a rigorous and systematic approach to studying and understanding complex phenomena in the real world.
