Introduction
This comprehensive assessment is designed to prepare candidates for the WGU C207 Data-Driven Decision Making
Objective Assessment Exam. The exam evaluates a graduate's proficiency in applying quantitative analysis, statistical
tools, and quality metrics to inform strategic organizational decisions. Candidates will demonstrate their ability to
analyze data from business intelligence systems, evaluate alternatives using decision-analysis tools, and apply
appropriate techniques to improve performance. The assessment utilizes a multiple-choice and scenario-based format
to test both foundational knowledge and practical application. Emphasis is placed on critical thinking, ethical
considerations, and the ability to translate data insights into professional, real-world decisions that enhance
organizational effectiveness.
Question 1
Data-driven decision making primarily aims to achieve what organizational outcome?
A. Eliminate the need for managerial intuition
,B. Reduce risk by making fact-based choices
C. Increase the volume of collected data
D. Automate all strategic planning processes
🟢 Correct Answer: B. Reduce risk by making fact-based choices
🔴 Explanation: The primary purpose of quantitative analysis in business is to enable managers to make fact-based
decisions that reduce risk and inform strategic choices. Data analysis supports, rather than replaces, managerial
judgment, and its goal is informed decision-making, not simply data accumulation or full automation.
Question 2
A marketing manager reviews historical sales data to determine which product categories had the highest sales
volume last quarter. This is an example of which type of analytics?
A. Predictive analytics
B. Prescriptive analytics
C. Descriptive analytics
D. Diagnostic analytics
🟢 Correct Answer: C. Descriptive analytics
🔴 Explanation: Descriptive analytics summarizes and describes past data to understand what has happened. In this
scenario, the manager is examining historical data to identify sales trends, which is the primary function of
descriptive analytics. Predictive analytics forecasts the future, while prescriptive analytics recommends actions.
Question 3
A healthcare system is implementing a new patient record system. Which term describes the ability of the new
system to consistently produce the same patient data results under the same conditions?
A. Validity
B. Reliability
C. Accuracy
D. Precision
,🟢 Correct Answer: B. Reliability
🔴 Explanation: Reliability refers to the consistency and repeatability of a measurement instrument . The new system
consistently producing the same results under the same conditions demonstrates high reliability. Validity refers to
whether the instrument measures what it is intended to measure, which is a different concept.
Question 4
Which of the following is a key characteristic of a well-defined, measurable business question for a data analysis
project?
A. It is broad and open to interpretation
B. It is specific and focuses on a single metric
C. It is based on unverifiable assumptions
D. It is designed to confirm a pre-existing bias
🟢 Correct Answer: B. It is specific and focuses on a single metric
🔴 Explanation: A well-defined business question should be specific, focused, and measurable to guide the data
collection and analysis process effectively. A broad or ambiguous question makes it difficult to select appropriate
data and analytical methods. The goal is objective inquiry, not confirmation of a pre-existing bias.
Question 5
A manufacturing firm uses a control chart to monitor the weight of its packaged products. The chart shows a point
that falls outside the upper control limit. What is the most appropriate initial action?
A. Immediately shut down the entire production line
B. Investigate the process for special cause variation
C. Ignore the point as it is likely a random error
D. Adjust the control limits to include the new point
🟢 Correct Answer: B. Investigate the process for special cause variation
🔴 Explanation: A point outside the control limits indicates the presence of a "special cause" or assignable cause of
variation. The correct action is to investigate the process to identify and correct the source of this variation. Control
, limits are designed to distinguish between common and special cause variation, and they should not be adjusted
arbitrarily.
Question 6
A company is deciding between two potential suppliers. They use a decision matrix to score each supplier on cost,
quality, delivery time, and customer service. What is the primary advantage of using this tool?
A. It provides a quantitative and structured comparison
B. It eliminates the need for qualitative input
C. It guarantees the selection of the optimal supplier
D. It simplifies the decision to a single criterion
🟢 Correct Answer: A. It provides a quantitative and structured comparison
🔴 Explanation: A decision matrix provides a structured, quantitative framework for comparing multiple alternatives
against a set of defined criteria. It helps to make the decision-making process more transparent and objective. It
does not eliminate the need for judgment or guarantee the optimal choice, as it is based on assigned weights and
scores.
Question 7
In a regression analysis, a p-value of 0.03 for a coefficient suggests:
A. There is a 3% probability that the coefficient is equal to zero
B. The coefficient is statistically significant at the 5% significance level
C. There is a 97% probability that the coefficient is zero
D. The model is a poor fit for the data
🟢 Correct Answer: B. The coefficient is statistically significant at the 5% significance level
🔴 Explanation: A p-value is the probability of observing the sample results (or more extreme) if the null hypothesis
is true. A p-value of 0.03 is less than the common significance level of 0.05, indicating that the null hypothesis (that
the coefficient is zero) can be rejected, and the coefficient is statistically significant .
