Abstract: This paper is aimed to explore key philosophical underpinnings of fundamental research paradigms with reference to Positivism and Interpretivism. It would Furthermore, outline and provide key interrelationships with the following: Ontology, Epistemology, Methodology and Method. The paper followed a literature review process and primarily supported by secondary research through inclusion and consideration of different peer reviewed academic papers relating to the subject as well as other publications such as books. Researchers can consider the fitness of each paradigm based on their research nature and context. This paper would support researchers to gain deeper understanding of the positivist and interpretivist paradigms. The interpretivist paradigm would enable researchers to gain further depth through seeking experiences and perceptions of a particular social context. The positivist paradigm on the other hand, would enable researchers to have more statistical reliance and generalisation leading to development of universal laws and findings.
