Research is defined as a systematic, scientific investigation that follows a sequence of steps to establish facts and solve problems. The objectives of research are to gain familiarity with phenomena, accurately portray characteristics of individuals or groups, or test hypotheses about causal relationships. A research paradigm provides the philosophical framework for how a researcher views the world and their research. The key aspects of a paradigm are its ontology regarding the nature of reality, epistemology regarding what can be known, and methodology regarding how knowledge can be obtained. Different paradigms like positivism, interpretivism, and critical theory have distinct beliefs about these aspects.
