The mixed methods paradigm is still in its adolescence. Therefore it is still relatively unknown and many researchers find it confusing. Mixed methods research represents a research method that involves collecting, analysing, and interpreting quantitative and qualitative data in a single study or a series of studies that investigate the same underlying phenomenon. This is done to answer the research questions with the view of drawing on inferences using both qualitative and quantitative approaches. The purpose of the article is to position mixed methods research as a third paradigm in research and as a natural complement to traditional qualitative and quantitative research methods. The designs that are currently used leave the novice researcher – and even the experienced researcher who is new to the field of mixed methods research – with the challenge of selecting optimal mixed methods designs.
