The purpose of this work is to investigate the main philosophical underpinnings of major research paradigms using Positivism and Interpretivism as examples. It would also explain and give crucial interrelationships with ontology, epistemology, methodology, and method. The study followed a literature review approach and was mostly supported by secondary research, which included the incorporation and consideration of many peer-reviewed academic papers relevant to the issue as well as other sources such as books. Researchers might examine the fitness of every model based on the nature and context of their study. This work will assist scholars in developing a better grasp of both positivist and interpretivist perspectives. The interpretivist paradigm might allow researchers to go deeper by seeking perceptions and experiences of a specific social context. The positivist paradigm, on the other hand, will allow researchers to rely more on statistics and generalization, resulting in the formation of universal rules and discoveries.
