D 514 Final Exam V3 | D 514 Analytical Methods of
Healthcare Leaders | Actual Q&A with Rationale
(D514 Final Exam) | Western Governors University
1. A healthcare leader is reviewing patient satisfaction scores which are ranked as ‘Very
Satisfied,’ ‘Satisfied,’ ‘Neutral,’ ‘Dissatisfied,’ and ‘Very Dissatisfied.’ Which level of
measurement does this data represent?
A. Nominal
B. Ratio
C. Interval
D. Ordinal
Correct Answer: D
Explanation: Ordinal data represents categories that have a logical or natural order but do
not have a standard mathematical distance between them. In healthcare, patient
satisfaction surveys are a primary example of ordinal data because while ‘Satisfied’ is
better than ‘Neutral,’ the difference cannot be quantified exactly. Leaders must use non-
parametric statistics or median values to analyze this specific type of data correctly.
2. When evaluating the standard deviation of patient wait times in the Emergency
Department, a leader finds a very high value. What does this indicate about the process?
A. There is a high degree of variation in wait times.
B. The process is highly efficient and predictable.
,C. The average wait time is low.
D. The median and the mean are identical.
Correct Answer: A
Explanation: Standard deviation is a measure of dispersion that quantifies how much data
points differ from the mean. A high standard deviation indicates that patient wait times
vary significantly, suggesting instability or inconsistency in the department’s workflow.
Reducing this variation is a key goal in Lean and Six Sigma methodologies used within
healthcare systems.
3. In a hypothesis test, if the p-value is 0.03 and the alpha level is set at 0.05, what should the
researcher conclude?
A. The test results are inconclusive.
B. Fail to reject the null hypothesis.
C. Accept the null hypothesis as true.
D. Reject the null hypothesis.
Correct Answer: D
Explanation: A p-value lower than the alpha level indicates that the observed result is
statistically significant and unlikely to have occurred by chance. Therefore, the healthcare
leader should reject the null hypothesis in favor of the alternative hypothesis. This
decision-making process is fundamental to evidence-based management when evaluating
the efficacy of new clinical protocols.
, 4. Which quality improvement tool is specifically designed to identify the ‘vital few’ problems
by showing that 80% of effects come from 20% of causes?
A. Control Chart
B. Pareto Chart
C. Fishbone Diagram
D. Scatter Plot
Correct Answer: B
Explanation: The Pareto Chart is based on the 80/20 rule, helping healthcare leaders
prioritize which issues will yield the greatest improvement if resolved. By plotting
frequencies in descending order, it visually separates the ‘vital few’ from the ‘useful many.’
This tool is essential for resource allocation when multiple quality gaps exist
simultaneously.
5. A hospital wants to monitor the number of medication errors per 1,000 patient days. Since
the number of patient days varies each month, which control chart should be used?
A. P-chart
B. R-chart
C. X-bar chart
D. U-chart
Correct Answer: D
