Q&A with Rationale (D514 Exam 1) |
Western Governors University
1. A healthcare administrator is categorizing patients by their primary insurance provider
(e.g., Medicare, Medicaid, Private). Which level of data measurement is being used?
A. Ratio
B. Interval
C. Nominal
D. Ordinal
Answer: C
Rationale: Nominal data represents categories that do not have a natural order or ranking.
Since insurance types are distinct labels without a mathematical hierarchy, they fit the
nominal classification. Using the correct level of measurement is essential for selecting the
appropriate statistical test in healthcare analytics.
2. When analyzing patient satisfaction scores on a Likert scale from 1 to 5, which level of
measurement is most appropriate?
A. Nominal
B. Interval
,C. Ratio
D. Ordinal
Answer: D
Rationale: Ordinal data involves categories that have a clear, logical order but the intervals
between them are not necessarily equal. Patient satisfaction ratings like ‘satisfied’ to
‘dissatisfied’ represent this hierarchy perfectly. Healthcare leaders use ordinal data to track
qualitative improvements in service delivery.
3. A researcher measures the body temperature of patients in degrees Fahrenheit. This is an
example of which level of measurement?
A. Nominal
B. Ratio
C. Interval
D. Ordinal
Answer: C
Rationale: Interval data has a definite order and consistent intervals between values, but it
lacks a true zero point. Temperature in Fahrenheit or Celsius is a classic example because
zero degrees does not mean ‘no temperature.’ This distinction is vital when calculating
means and differences in clinical settings.
, 4. In a study measuring the length of stay for hospital patients in days, which level of
measurement is applied?
A. Nominal
B. Ordinal
C. Ratio
D. Interval
Answer: C
Rationale: Ratio data possesses all the characteristics of interval data but includes a true
zero point, representing the total absence of the variable. Length of stay can be zero (e.g.,
outpatient), and ten days is exactly twice as long as five days. Healthcare analysts prefer
ratio data for its high level of mathematical flexibility.
5. A facility’s readmission rate has been tracked for 12 months. If the distribution of rates is
highly skewed by one extremely high month, which measure of central tendency should the
leader report?
A. Mean
B. Median
C. Mode
D. Standard Deviation
Answer: B
