D 514 Final Exam V1 | D 514 Analytical Methods of
Healthcare Leaders | Actual Q&A with Rationale
(D514 Final Exam) | Western Governors University
1. A healthcare administrator is categorizing patients by their primary insurance provider
(e.g., Medicare, Medicaid, Private, Uninsured). What level of data measurement is being
used?
A. Ordinal
B. Interval
C. Nominal
D. Ratio
Correct Answer: C
Explanation: Nominal data is used for labeling variables without any quantitative value or
order. In this scenario, insurance types are distinct categories that do not have a natural
ranking. This type of measurement is fundamental for descriptive statistics in healthcare
administration.
2. Which measure of central tendency is most sensitive to extreme outliers in a dataset
representing patient wait times?
A. Mode
B. Median
,C. Mean
D. Standard Deviation
Correct Answer: C
Explanation: The mean is calculated by summing all values and dividing by the count,
making it highly susceptible to skewed data. When extreme outliers are present, the mean
may not accurately reflect the typical patient experience. Administrators often use the
median instead to provide a more representative center for skewed distributions.
3. An analyst discovers that as the number of nurses on a floor increases, the number of
patient falls decreases. What type of relationship does this describe?
A. Negative correlation
B. Positive correlation
C. No correlation
D. Spurious correlation
Correct Answer: A
Explanation: A negative correlation occurs when one variable increases while the other
decreases. In this case, staffing levels and safety incidents move in opposite directions. This
insight is crucial for resource allocation and improving patient outcomes.
4. In a hypothesis test, what does the p-value represent?
A. The probability that the null hypothesis is true.
, B. The probability of observing the results if the null hypothesis is true.
C. The probability that the research hypothesis is false.
D. The effect size of the intervention.
Correct Answer: B
Explanation: The p-value measures the strength of evidence against the null hypothesis. A
low p-value suggests that the observed data is unlikely to have occurred by chance alone
under the null. Typically, a p-value less than 0.05 is considered statistically significant in
healthcare research.
5. A Quality Improvement team uses a chart to identify the ‘vital few’ problems that account
for the majority of patient complaints. Which tool are they using?
A. Fishbone Diagram
B. Control Chart
C. Scatter Plot
D. Pareto Chart
Correct Answer: D
Explanation: The Pareto Chart is based on the 80/20 rule, which suggests that 80% of
problems result from 20% of causes. It helps healthcare leaders prioritize interventions by
visualizing the frequency of issues. By focusing on the tallest bars, teams can achieve the
greatest impact with their resources.
