WGU C224 Research Foundations &
Methodologies Objective Assessment – Latest
Exam with Complete 350 Questions and
Verified Answers
Official Exam Overview:
The WGU C224 OA evaluates learners’ understanding of research principles, methodologies, and
the application of quantitative, qualitative, and mixed-methods designs. The exam emphasizes the
ability to analyze, interpret, and integrate research findings, with a focus on sampling,
implementation, and the purpose of various mixed-method approaches in guiding evidence-based
decision-making.
Exam Coverage Areas:
• Research methodology: qualitative, quantitative, and mixed methods
• Mixed-methods designs: explanatory, exploratory, and development purposes
• Sampling strategies and implementation techniques
• Data collection, analysis, and integration of results
• Ethical considerations in research
• Interpreting results to inform practice or subsequent studies
• Evidence-based application of research findings
QUESTION 1:
Which mixed research purpose seeks to "use the results from one method to inform the other
method" by including sampling and implementation?
A) Explanatory
B) Exploratory
C) Development ✅
D) Evaluation
Rationale:
The development purpose in mixed-method research uses findings from one method to inform
the design, sampling, or implementation of the other method, ensuring integration and coherence
between qualitative and quantitative components.
QUESTION 2:
In mixed-method research, what is the main goal of an explanatory design?
,A) To develop new tools
B) To explain quantitative results with qualitative data ✅
C) To explore unknown phenomena
D) To evaluate program outcomes
Rationale:
An explanatory design starts with quantitative results and uses qualitative data to clarify or
explain those results in depth.
QUESTION 3:
Which of the following best describes exploratory mixed-method research?
A) Begins with quantitative data
B) Begins with qualitative data to inform quantitative study ✅
C) Combines results for statistical analysis
D) Focuses only on implementation
Rationale:
Exploratory designs start with qualitative methods to gain insights, which then guide quantitative
sampling or measurement.
QUESTION 4:
Why is sampling important in mixed-method research?
A) It ensures only qualitative data is used
B) It allows integration of findings across methods ✅
C) It eliminates the need for ethical approval
D) It guarantees significant results
Rationale:
Sampling strategies ensure that data collected in both methods can be effectively compared and
integrated, supporting valid mixed-method conclusions.
QUESTION 5:
Which statement about mixed-method research is correct?
A) Quantitative and qualitative data are always collected simultaneously
B) One method can be used to inform or enhance the other ✅
C) Mixed-method research ignores sampling techniques
D) Only statistical analysis is necessary
Rationale:
Mixed-method research integrates qualitative and quantitative approaches, often using one
method to inform or guide the other, enhancing validity and depth of findings.
Which of the following mixed research purposes seek to "use the results from one method to
,inform the other method" by including sampling and implementation? - ANSWER-Development
If a mixed research study uses a nested concurrent sampling design, then which of the following
best represents this design? - ANSWER-Quantitative and qualitative data being collected at the
same time, but with the qualitative sample being a subset of the quantitative sample.
Which analysis procedure focuses on decreasing the number of dimensions in the quantitative
and/or qualitative data? - ANSWER-Data reduction
Which of the following is best represented by quantitative and qualitative data and qualitative
data analysis techniques are used in the same research study? - ANSWER-Mixed data analysis
When a researcher can use the strengths of an additional method to overcome the limitations
in another method, this is known as what? - ANSWER-Principle of nonoverlapping weaknesses
Some details of mixed research remaining to be worked out by research methodologists,
including problems of paradigm mixing, how to interpret conflicting results and which of the
following? - ANSWER-Mixed data analysis
Through the combination of more than one research methods in a single study, researchers can
ensure that what occurs? - ANSWER-They will avoid making a mistake
The compatibility thesis states that quantitative and qualitative approaches can be used
together in a single research study as long as researchers construct a thoughtful combination

that will help to address their research question, as well as adhere to which of the following? -
ANSWER-Respect for the assumptions of each method equally
Which of the following mixed research purposes seek to "broaden the breadth and range of
inquiry" by combining research methods? - ANSWER-Expansion
If a mixed research study uses a nested sequential sampling design, then which of the following
best represents this design? - ANSWER-Quantitative and qualitative data are collected one after
the other, but with the quantitative sample being a subset of the qualitative sample.
All of the following are types of mixed data analysis except? - ANSWER-Monodata-
monoanalysis
Which phrase refers to a researcher providing stronger evidence for a conclusion through
convergence and corroboration of findings? - ANSWER-Which phrase refers to a researcher
providing stronger evidence for a conclusion through convergence and corroboration of
findings?
There are still some details of mixed research which remain to be worked out by research
methodologists, including all of the following except: - ANSWER-Techniques for quantitatively
analyzing qualitative data
When qualitative and quantitative data are analyzed using qualitative techniques within a single
study, this is reflective of which of the following? - ANSWER-Multidata-Monoanalysis
Which analysis procedure focuses on taking quantitative and qualitative data findings and
building a coherent whole? - ANSWER-Data integration
An action researcher develops an action research attitude when they consider areas of possible
improvement, unique tactics to attempt, and .... - ANSWER-potential consequences
