D 514 Exam 4 V1 | D 514 Analytical Methods of
Healthcare Leaders | Actual Q&A with Rationale
(D514 Exam 4) | Western Governors University
1. A healthcare leader is analyzing the frequency of patient falls across different wards. Which
graphical tool should be used to distinguish the ‘vital few’ causes of falls from the ‘trivial
many’?
A. Control Chart
B. Scatter Diagram
C. Pareto Chart
D. Histogram
Correct Answer: C
Explanation: The Pareto Chart is based on the 80/20 rule, which suggests that most effects
come from a minority of causes. By ranking the causes of falls from highest to lowest
frequency, the leader can identify which areas require immediate intervention. This tool is
essential for prioritizing quality improvement efforts when resources are limited.
2. When evaluating a clinical process, a manager observes data points that fall outside the
upper control limit on a Shewhart chart. This is an example of:
A. Common cause variation
B. Normal distribution variance
,C. Standard process drift
D. Special cause variation
Correct Answer: D
Explanation: Special cause variation refers to fluctuations in a process that are not
inherent and are caused by specific, identifiable events. In a control chart, points outside
the control limits or specific patterns indicate that the process is ‘out of control’ due to
these external factors. Identifying special cause variation is the first step in stabilizing a
process before long-term improvements can be made.
3. Which level of measurement is being used when a researcher categorizes patients by their
primary health insurance provider (e.g., Medicare, Medicaid, Private)?
A. Ordinal
B. Interval
C. Ratio
D. Nominal
Correct Answer: D
Explanation: Nominal data represents categories that do not have an inherent numerical
value or specific order. In this case, insurance providers are labels used to group data
without implying that one is ‘higher’ or ‘lower’ than another. Understanding the level of
measurement is critical for selecting the appropriate statistical test for analysis.
, 4. In a Six Sigma project, which phase of the DMAIC process involves identifying the root
causes of defects and verifying them through data analysis?
A. Define
B. Measure
C. Improve
D. Analyze
Correct Answer: D
Explanation: The Analyze phase focuses on using statistical tools to identify the ‘red X’ or
the primary source of variation in a process. During this stage, project teams move beyond
symptoms to find the underlying reasons why defects occur. Successful completion of this
phase ensures that subsequent improvements target the actual cause rather than just the
symptoms.
5. A healthcare organization is implementing an Information Governance (IG) program.
According to the AHIMA IGPHC principles, which principle requires the organization to
document its processes and activities in a verifiable manner?
A. Transparency
B. Accountability
C. Integrity
D. Disposition
