Abstract:
The purpose of this article is to present the evaluative criteria of qualitative and quantitative research. Philosophical foundations of positivism, postpositivism and constructivism are explored. Triangulation and crystallization expose the controversies about them. Finally, Lincoln and Guba criteria are retained for the evaluation of qualitative and quantitative research.
