2. What is mixed methods and why?
 A procedure for collecting, analysing, and “mixing” both quantitative and qualitative
methods in a single study or a series of studies to understand a research problem
(Creswell & Plano Clark, 2011).
 Used MMR when:
a. When we have both qualitative & quantitative data.
b. When one type of research design is not sufficient to answer or explain the RQs.
c. When you need qualitative research to help explain quantitative findings.
d. When you want to obtain more detailed, specific information than can be gained
from the results of statistical tests.
e. When you want to provide an alternative perspective in a study.

3. Notations of Mixed Methods

4. Types of mixed methods
Convergent
parallel design
Explanatory
sequential
design
Exploratory
sequential
design
Embedded
design
Transformative
design
Multiphase
design

5. Purpose: To simultaneously collect both quantitative and qualitative data, merge the data,
and use the results to understand a research problem.
Convergent (concurrent) parallel design

6. The Explanatory Sequential Design
(two phase model)
• First, collecting quantitative data then collecting qualitative data to help explain or
elaborate on the quantitative results.
• Purpose: To use qualitative results to assist the finding of a quantitative research.

7. The Exploratory Sequential Design
First, collecting the qualitative data to explore a phenomenon, then collecting quantitative
data to explore the relationship found in the qualitative data.
Purpose: To explore a phenomenon. May also be useful when developing and testing new
instrument.

8. Purpose: to collect quantitative and qualitative data simultaneously or sequentially, but to
have one form of data play a supportive role to the other form of data.

9. The Transformative Design
Purpose: To use one of the four designs (convergent, explanatory, exploratory, or
embedded), but to encase the design within a transformative framework or lens.

10. The Multiphase Design
• A complex design, builds on the basic convergent, explanatory, exploratory, and
embedded design.
• Use when researchers examine a problem or topic through a series of phases or
separated studies.

11. Basic characteristics of MM
• Provide the rationale for the design.
• Include collecting qualitative and quantitative data.
• Consider priority.
• Consider sequence.
• Match the data analysis to a design.
• Diagram the procedures.

13. HOW DO YOU EVALUATE A MIXED METHODS
STUDY?
• Describes that mixed methods is the best approach to answer the research questions.
• Incorporates both qualitative and quantitative data collection and analysis.
• Explicitly combines or mixes the two datasets.
• Uses rigorous quantitative and persuasive qualitative procedures of data collection and
analysis.
• Frames the study within one of the mixed methods research designs.
• Provides a diagram of the procedures to clarify the timing, priority, and mixing
• within the study.
• Signals to the reader that the study is using mixed methods.

14. POTENTIAL ETHICAL ISSUES IN MM
RESEARCH DESIGN
• Quantitative: obtaining permissions, protecting anonymity of respondents, not disrupting
sites, and communicating the purposes for the study.
• Qualitative: conveying the purpose of the study, avoiding deceptive practices, respecting
vulnerable populations, respecting indigenous cultures, not disclosing sensitive information,
etc.
• Convergent design: care needs to be taken to not minimize the importance of a sample
because of its size.

15. • Explanatory design: in order to follow up on those individuals with qualitative interviews,
there needs to be an identifier linked to the quantitative database; do not use names with
permission.
• Embedded design: do not use the initial interview data to place participants into a control
group where they do not receive a beneficial treatment.
