quantitative/qualitative research, sampling,
validity, statistics, ethics, and action research
with verified answers and rationales for the
WGU C224 Objective Assessment.
Mixed Methods Research
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
Correct ☑VERIFIED ANSWER: C)
Development
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
Correct ☑VERIFIED ANSWER: B) To explain
quantitative results with qualitative data
Rationale: An explanatory design starts with
quantitative results and uses qualitative data to
clarify or explain those results in depth .
Question 3
Which 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
Correct ☑VERIFIED ANSWER: B) Begins
with qualitative data to inform quantitative
study
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
