Mixed Methods Research
Mixed methods research is a growing area of methodological choice for many academics and researchers from
across a variety of discipline areas. With the development and perceived the legitimacy of both quantitative and qualitative research in the social and
human sciences, mixed methods research, employing the combination of both
quantitative and qualitative research has gained popularity. This popularity
is because research methodology continues to evolve and develop and mixed methods
research is another step forward, utilizing the strengths of both qualitative
and quantitative methods.
Mixed methods research is
basically defined as the class of research where the researcher mixes or
combines quantitative and qualitative research techniques, methods, approaches,
concepts or language into a single study. Philosophically, it is the “third
wave” or third research movement, a movement that moves past the paradigm wars
by offering a logical and practical alternative. It is an expansive and
creative form of research, not a limiting form of research. It is inclusive,
pluralistic and complementary. Mixed methods research focuses on collecting,
analyzing and mixing both quantitative and qualitative data in a single study
or series of studies. Its central premise is that the use of quantitative and
qualitative approaches in combination provides a better understanding of
research problems that either approach alone. This better understanding results
because mixed methods offer strengths that offset the weaknesses of separately
applied quantitative and qualitative research methods. It also encourages the
collection of more comprehensive evidence for study problems; helps answer
questions that quantitative or qualitative methods alone cannot answer. Mixed
methods research is important today because of the complexity of problems that
need to be addressed, the rise of interest in qualitative research and the
practical need to gather multiple forms of data for diverse audiences.
Johnson, Onwuegbuzie and Turner
define mixed methods research “is the type of research in which a researcher or
a team of researchers combines elements of quantitative and qualitative
approaches (e.g. use of qualitative and quantitative viewpoints, data
collection, analysis, and inference techniques) for the purpose of breadth and
depth of understanding and corroboration”. Also, the Journal of Mixed Methods,
in its call for paper mixed methods defined mixed methods research as “research
in which investigator collects, analyses, mixes and draws inferences from both
qualitative and quantitative data in a single study or a program of inquiry”.
Qualitative and Quantitative Data
As per the definition, mixed methods research involves both
collecting and analyzing quantitative and qualitative data. Quantitative data
includes closed-ended information such as that found on attitude, behaviour, or
performance instruments. Sometimes quantitative information is found in
documents such as census records or attendance records. The analysis consists
of statistically analyzing scores collected on instruments, checklists or
public documents to answer research questions or to test hypotheses.
In
contrast, qualitative data consists of open-ended information that researcher
gathers through interviews with participants. The general, open-ended questions
asked during these interviews allow the participants to supply answers in their
own words. Also, qualitative data may be collected by observing participants or
sites of research, gathering document from a private or public source, etc. The
analysis of the qualitative data (word or text or images) typically follows the
path of aggregating the words or images into categories of information and
presenting the diversity of ideas gathered during data collection.
Mixing of Data
The
mixing of data is a unique aspect of the definition of the mixed methods
research. By mixing the datasets, the researcher provides a better
understanding of the problem than if either data set had been used alone. There
are three ways in which the mixing occurs: merging or converging the two data
sets by actually bringing them together, connecting the two datasets by having
built on the other, or embedding one dataset within the other so that one type
of data provides a supportive role for the other dataset. In short, it is not
enough to simply collect and analyze qualitative and quantitative data; they
need to be mixed in some way so that together they form a more complete picture
than they do when standing alone.

Basic Characteristics
- Design can be based on either
or both perspectives.
- Research problems can become
research questions and/or hypotheses based on prior literature, knowledge,
experience, or the research process.
- Sample sizes vary based on
methods used.
- Data collection can involve any
technique available to researchers.
- Interpretation is continual and
can influence stages in the research process(‘Mixed
Methods Research Designs | Research Rundowns’, n.d.).
Mixed Methods Research Process Model
The
mixed methods research process model comprises eight distinct steps:
- Interpretation of data;
- Analysis of data;
- Collection of data;
- Selection of mixed-method or
mixed-model research design;
- Determining the research question;
- Determining whether a mixed the research procedure is appropriate;
- Legitimization of data; and
- Drawing conclusions and writing
the final report(kudrat, 2015).

Why Use Mixed Methods?
The simple the answer is to overcome the limitations of a single design. A detailed answer
involves:
·
To
explain and interpret.
·
To
explore a phenomenon.
·
To
develop and test a new instrument.
·
To
serve a theoretical perspective.
·
To
complement the strengths of a single design.
·
To
overcome the weaknesses of a single design.
·
To
address a question at different levels.
·
To
address a theoretical perspective at different levels.
What are some strengths?
- Can be easy to describe and to
report.
- Can be useful when unexpected
results arise from a prior study.
- Can help generalize, to a
degree, qualitative data.
- Helpful in designing and
validating an instrument.
- Can position research in a
transformative framework.
What are some weaknesses?
- Time required.
- Resolving discrepancies between
different types of data.
- Some designs generate unequal
evidence.
- Can be difficult to decide when
to proceed in sequential designs.
- Little guidance on
transformative methods.
TYPES
Sequential
explanatory design. This design involves the collection
and analysis of ofquantitative data followed by the collection and analysis of
qualitative data. The priority is given to the quantitative data, and
the findings are integrated during the interpretation phase of the
study.
Example: The
researcher collects data about people’s risk and benefit perceptions of red
meat using a survey and follows up with interviews with a few individuals who
participated in the survey to learn in more detail about their survey responses
(e.g., to understand the thought process of people with low-risk perceptions
(‘Mixed
methods research’, n.d.).
sequential exploratory design. In
this design, qualitative data
collection and analysis is followed by quantitative data collection and analysis.
The priority is given to the qualitative aspect of the study, and the findings
are integrated during the interpretation phase of the study
Example: The
researcher explores people's beliefs and knowledge regarding nutritional
information by starting with in-store interviews and then uses an analysis of
the information to develop a survey instrument that is administered later to a
sample from a population.
Concurrent triangulation. In this
design only one data collection phase is used, during which quantitative
and qualitative data collection and analysis are conducted separately yetconcurrently.
The findings are integrated during the interpretation phase of the study.
Usually, equal priority is given to both types of research.
Example:The
researcher uses a survey to assess people’s self-reported food safety practices
and also observes those practices in their natural environment. By comparing
the two types of data, the researcher can see if there is a match between what
people think they are doing and what they are actually doing in terms of food
safety practices.
Concurrent nested. In this design only
one data collection phase is used, during which a predominant method
(quantitative or qualitative) nests or embeds the other less prioritymethod
(qualitative or quantitative, respectively). This nesting may mean
that the embedded method addresses a different question than the dominant
method or seeks information from different levels. The data collected from the
two methods are mixed during the analysis phase of the project.
Example:The
researcher collects data to assess people’s knowledge and risk perceptions
about genetically modified food by using a survey instrument that mixes
qualitative (open-ended) and quantitative (closed-ended) questions, and both
forms of data are integrated and analysed.
Conclusion
Mixed methods research actually has a long history
in research practice. It is now time that all researchers and research
methodologists formally recognize the third research paradigm and begin systematically
writing about it and using it. Generally, a contingency theory is recommended
for research approach selection, which accepts that quantitative, qualitative
and mixed research are all superior under different circumstances and it is the
researcher’s task to examine the specific contingencies and make the decision
about which research approach or combination of approaches, should be used in a
specific study. As noted by Sechrest and Sidana, growth in the mixed method
movements has the potential to reduce some of the problems associated with
singular methods. By narrowing the divide between quantitative and qualitative
researches, mixed method research has a great potential to promote a shared
responsibility in the quest for attaining accountability for educational
quality. The time has come for mixed methods research.
