Those are: Qualitative Method Research, Quantitative Method Research, and Mixed Method Research. Each method has its own peculiarities in terms of strengths and weaknesses. However, this article focuses only on mixed research methodology. So, what is mixed methods research? Second There are two main reasons why this mixed methods research is chosen to answer the research question, including minimizing the gap of missing data from quantitative or qualitative method and generating better results of the research question more than one method. The first main The reason for choosing mixed methods research is that multiple methods research can minimize the gap of missing data from qualitative and quantitative method approaches. As McLaughlin (1991) explains in his article, in most cases, researchers use a qualitative research approach to discover some findings after conducting quantitative research. Some researchers use the quantitative method after conducting research on the qualitative method, before filling gaps in data analysis (McLaughlin, 1991, pp.303-304). Johnson and Onwuegbuzie (2007) (as cited in Connelly (2009) state that the mixed methods approach provides a space for researchers to be able to answer more complex research questions because they use both methods for survey research ( Connelly, 2009,
