As stated in the first part of article, we have stated the four major philosophical paradigms which make up the basis for knowledge (epistemology), the nature and reality (ontology) and the acquisition methods of knowledge (methodology). Thus, according to each paradigm, approach to knowledge is determined.
In a more general category, we have two quantitative and qualitative paradigms. Today that method is called quantitative or scientific method, derived from positivism. On this basis, only the experimental scientific method is valid method of research. On the other hand, qualitative methods focused on natural position, therefore, these studies are sometimes called naturalistic study.
Since paradigmatic confrontation occurs in fundamental questions of each paradigm, researchers use different sources to determine two paradigms' answer to basic questions, and tables are made to comprise them. Finally the importance of each was emphasized.
