Q1 Question 1 of 50
Q1. A graduate student surveys 200 clinic patients and reports their average age along with a bar chart
of visit reasons. The summary uses only the collected data without projecting to a larger group. Which
branch of statistics does this work represent?
A. Descriptive statistics, because the data are summarized without generalizing
B. Inferential statistics, because conclusions extend beyond the sample
C. Probability theory, because random processes are modeled
D. Bayesian analysis, because prior distributions are updated
Correct Answer: A
Rationale:
Descriptive statistics organize, summarize, and display data from a sample or population without making inferences
beyond it. Inferential statistics would generalize from the sample to a larger population, which is not what is described in
this scenario.
Q2 Question 2 of 50
Q2. During a preoperative screening of 50 surgical candidates, the circulating nurse records each
patient's blood type as A, B, AB, or O for transfusion planning. What type of variable is blood type?
A. Quantitative continuous
B. Quantitative discrete
C. Qualitative ordinal
D. Qualitative nominal
Correct Answer: D
Rationale:
Blood type is a label with no inherent ordering, making it a qualitative nominal variable. Ordinal implies order, while
quantitative variables involve counts or measurements.

, Q3 Question 3 of 50
Q3. An emergency department logs 24 admissions on Monday, 31 on Tuesday, and 18 on Wednesday
as part of a staffing analysis. What kind of variable is the daily admission count?
A. Continuous, because admissions occur over time
B. Continuous, because the day has 24 hours
C. Discrete, because the values are countable whole numbers
D. Discrete, because each admission has a unique ID
Correct Answer: C
Rationale:
Daily admission counts are whole numbers obtained by counting events, which defines a discrete quantitative variable.
Continuous variables arise from measurements that can take any value within a range.
Q4 Question 4 of 50
Q4. A hospice nurse asks patients to rate their pain on a 0 (no pain) to 10 (worst imaginable pain) scale
at each assessment. Pain rating on this scale represents which level of measurement?
A. Nominal
B. Ordinal
C. Interval
D. Ratio
Correct Answer: B
Rationale:
Pain ratings have an inherent order but the differences between values are not necessarily equal in a true numeric sense,
and there is no meaningful zero point. This makes the scale ordinal.
Q5 Question 5 of 50
Q5. A research assistant records the morning body temperature of 30 inpatients in degrees Celsius as
part of a fever-surveillance protocol. What level of measurement does Celsius temperature represent?
A. Interval
B. Nominal
C. Ratio
D. Ordinal
Correct Answer: A
Rationale:
Celsius temperature has equal intervals between values but an arbitrary zero point (0 C does not mean absence of heat),
which defines the interval level. Ratio level would require a true zero, like Kelvin.
