Greene, Caracelli, and Graham (1989) suggest that five major objectives or motivations exist for conducting MMR. The first one is ‘triangulation’, which provides validation and concurrence of results gained from various methods and designs investigating the same circumstance. ‘Complementarity’, as the second motivation, seeks for further detailing, improvement, interpretation and description of the results obtained from one method with results from the other method. The third one is ‘initiation’, which means unearthing the bias, and discrepancies that cause re-designing of the research question. ‘Development’, the fourth motivation, includes utilizing the findings from one method to deliver clues to other method. The last motivation, ‘expansion’, seeks to expand the size of research with different methods for different investigation factors.

The weaknesses of the MMR are as follows:

The other options reflect the strengths of mixed methods research.

MMR can be defined as the combination of quantitative and qualitative methods for a clear understanding of research objectives than either approach alone. It is because MMR balances the weaknesses of quantitative and qualitative research and transforms them into strength. By using all types of data collection tools, researchers can get more comprehensive evidence for a research problem. On the other hand, MMR enables researchers to answer questions that cannot be answered by qualitative or quantitative approaches alone. MMR can be so functional that the researchers feel free to make use of different methodologies to reach the research objectives. It is possible to use words, pictures and narrative to add meaning to numbers in MMR. Requiring more than one research is considered as a weakness of mixed methods research.

Johnson and Onwuegbuzie (2004) propose a process of MMR including eight specific steps, respectively designating the research question, specifying whether a mixed design is appropriate, choosing the mixed method or mixed model research design, gathering the data, clarifying the data, validating the data, coming to a conclusion and writing the final report.

After deciding that MMR is suitable for the study, the researchers determine their rationale for using a mixed design. Participant enrichment involves blending quantitative and qualitative research to better the sample using approaches that encompass recruiting participants, dealing with activities such as institutional review board interviews assuring that each participant chosen is eligible for involvement. Triangulation seeks convergence, correspondence, and corroboration of results from different methods studying the same phenomenon. Instrument fidelity pertains to evaluating the convenience and/or effectuality of current instruments, by generating new instruments and observing performance of human instruments. Significance enhancement refers to interpretation and utility of findings.

MMR sampling process consists of seven steps:
