According To Greene & McClintock, The Mixed Method Is Divided Into Five Main Justifications. The First Justification Is The Validation: Triangulation Course Work, UU, Ireland

According to Greene & McClintock, the mixed method is divided into five main justifications. The first justification is the validation of results from diverse methods executed to investigate a particular problem statement. The second justification is the complementarity that seeks to improve and clarify the research findings gathered from both research approaches.

The third justification is the development of how the research findings help to build knowledge on the second method’s results. The fourth justification is the initiation which discovers the contradictors that may lead the author to reframe the research question. And last, the fifth justification refers to the expansion where the researcher seeks to grow the research with the use of different approaches.
