WGU C207 Data-Driven Decision-Making Objective Assessment Comprehensive Examination 2026/2027 | Verified Questions
,INTRODUCTION
This collection presents one hundred (100) original, university-level questions developed for the C207 Data-
Driven Decision-Making Objective Assessment Comprehensive Examination at Western Governors
University. The material is organized into four core domains: Framing the Problem and Data Collection;
Descriptive Statistics and Data Visualization; Inferential Statistics and Hypothesis Testing; and Predictive
Analytics and Business Decision Making. Every item is written to reinforce the official C207 Objective
Assessment Comprehensive Examination course objectives, supporting actual exam readiness and the
development of professional proficiency in framing business questions, preparing and summarizing data,
drawing valid conclusions, and translating findings into business decisions. All content is aligned to the
2026/2027 academic year and reflects standard business analytics method and evidence-based decision-
making standards.
ACTUAL QUESTIONS
Domain 1: Framing the Problem and Data Collection
Question 1. A regional retailer's leadership team opens a project by stating, 'Our online sales
are too low.' Which revision best frames this as an analytics-ready business problem?
A. A restatement that simply adds urgency, such as our online sales must improve immediately
B. A request for all available sales data from every system with no defined outcome
C. A statement that names the preferred solution, such as we need a redesigned website
D. A decision-focused statement that names the measurable outcome, the scope, and the comparison,
such as identifying which customer segments and product categories fall furthest below the regional
online conversion benchmark so a targeted intervention can be chosen
Correct Answer: D
Rationale: WGU C207 course materials frame a business problem before any data is gathered by
specifying the decision to be made, the measurable outcome, the scope, and the comparison group. Naming
a preferred solution or asking for every available dataset skips the framing step and usually produces
analysis that cannot support a decision.
Question 2. Which of the following is a directionally stated hypothesis rather than a research
question?
A. Why do customers abandon their shopping carts
B. Customers who receive the loyalty email have a higher mean monthly order value than customers
who do not
C. What factors are associated with customer loyalty
D. How do customers describe their experience with our service
Correct Answer: B
Rationale: A hypothesis states an expected relationship between variables in a form that can be supported
or not supported with data, whereas a research question asks what or why and is typically exploratory.
C207 course materials separate the two because only the hypothesis form maps directly onto formal
significance testing.
Question 3. A team studies how the depth of a promotional discount relates to the number of
units sold. Which variable classification is correct?
A. Units sold is the independent variable and discount depth is the dependent variable
B. Both variables are independent because they are measured in the same period
C. Neither variable can be classified without running a regression model first
D. Discount depth is the independent variable and units sold is the dependent variable
Correct Answer: D
Rationale: Per standard statistical method used in the C207 course materials, the independent variable is
the one that is manipulated or used to explain change, and the dependent variable is the outcome being
explained. Classification follows the logic of the business question rather than the software used, and it
determines which variable belongs on which axis and on which side of a model.

, Question 4. An analysis finds that stores with more employees generate more revenue, and a
manager concludes that hiring more employees will raise revenue. Which issue most
threatens this conclusion?
A. The sample size is too small to compute an average
B. Revenue is a categorical variable and cannot be averaged
C. A confounding variable, because larger stores in busier locations both employ more staff and generate
more revenue
D. The conclusion is safe because both variables were measured at the same time
Correct Answer: C
Rationale: A confounder is associated with both the explanatory variable and the outcome and can produce
or mask an apparent relationship. C207 course materials stress that observational data supports claims of
association, and a causal claim requires either random assignment or a design that credibly accounts for
the confounder.
Question 5. A firm surveys 400 of its 6,000 employees and reports an average engagement
score of 7.4. Which statement correctly describes these elements?
A. The 400 respondents are the population and 6,000 is the sample
B. The value 7.4 is a parameter because it was computed from a survey
C. The value 7.4 is the true population average because the sample was large
D. The 6,000 employees are the population, the 400 respondents are the sample, and 7.4 is a statistic
used to estimate the population parameter
Correct Answer: D
Rationale: WGU C207 course materials and standard business analytics method indicate that a population
is the full set of interest and a sample is the subset actually observed; a number describing a sample is a
statistic and a number describing the population is a parameter. Statistical inference uses the statistic,
together with its variability, to estimate the unknown parameter rather than claiming it is exact.
Question 6. Which procedure produces a simple random sample of 100 customers from a
database of 5,000?
A. Assign every customer a number and use a random number generator to select 100 distinct numbers,
giving every possible group of 100 the same chance of being chosen
B. Select the first 100 customers who respond to an email invitation
C. Choose every 50th record in the database beginning with record 1
D. Sort customers by lifetime value and take the top 100
Correct Answer: A
Rationale: Simple random sampling requires that every subset of the stated size has an equal chance of
selection, which removes systematic selection bias and is the foundation for the probability methods taught
in C207. Volunteer, systematic, and judgment selections may look similar but do not give every group an
equal chance.
Question 7. A university with four campuses of very different sizes wants to compare student
satisfaction across campuses. Which sampling method is most appropriate?
A. Cluster sampling using classrooms as groups
B. Convenience sampling of students in the main library
C. Stratified random sampling, drawing a random sample from within each campus so every campus is
represented
D. Systematic sampling from an alphabetical list of all students
Correct Answer: C
Rationale: Stratified sampling divides the population into meaningful groups and samples within each one,
guaranteeing representation of small groups and generally lowering the standard error when the groups
differ from one another. Cluster sampling samples whole groups for cost efficiency, and convenience
sampling cannot support inference to the population.
