D 514 Exam 3 V3 | D 514 Analytical Methods of
Healthcare Leaders | Actual Q&A with Rationale
(D514 Exam 3) | Western Governors University
1. A healthcare leader is analyzing a run chart that displays patient wait times over the last 20
weeks. If the chart shows six consecutive points increasing or decreasing, what specific
statistical observation does this indicate?
A. A shift in the process mean
B. A trend within the data
C. An astronomical point
D. Normal common cause variation
Correct Answer: B
Explanation: In run chart interpretation, a trend is defined by six or more consecutive
points consistently increasing or decreasing. This signal indicates that the process is
changing in a specific direction over time. Healthcare leaders use this to identify whether
improvement efforts are having a sustained impact on performance metrics.
2. When implementing a Six Sigma project to reduce medication errors, a team uses the
DMAIC framework. During which phase does the team identify the root causes of the
defects?
A. Analyze
B. Measure
,C. Define
D. Improve
Correct Answer: A
Explanation: The Analyze phase of DMAIC is focused on identifying the gap between
current performance and goal performance. During this stage, leaders use data to confirm
the root causes of errors or waste within the system. This step is critical before moving to
the Improve phase to ensure solutions address the actual source of the problem.
3. A hospital administrator is reviewing a Pareto chart regarding patient falls. If the chart
indicates that 80% of falls occur in three specific units, what principle is being demonstrated?
A. The principle of standard deviation
B. The law of diminishing returns
C. Regression to the mean
D. The vital few and the useful many
Correct Answer: D
Explanation: The Pareto principle suggests that 80% of effects come from 20% of causes,
often called the vital few. By focusing on these specific units, the leader can achieve the
most significant reduction in total patient falls. This analytical approach helps prioritize
resources in a healthcare environment where efficiency is paramount.
, 4. In the context of statistical process control, what characterizes ‘common cause variation’?
A. It is caused by a specific, identifiable event.
B. It is variation inherent to the process itself.
C. It results in points falling outside control limits.
D. It indicates an unstable and unpredictable process.
Correct Answer: B
Explanation: Common cause variation is the noise or normal fluctuation that is always
present in a stable system. It is predictable within certain limits and is not caused by
specific external factors. Healthcare leaders must recognize that attempting to fix common
cause variation through individual intervention is considered tampering and can worsen
the process.
5. Which type of healthcare analytics is specifically designed to answer the question, ‘What
will happen in the future?’
A. Predictive Analytics
B. Diagnostic Analytics
C. Descriptive Analytics
D. Prescriptive Analytics
Correct Answer: A
