INTRODUCTION
,This assessment evaluates foundational and applied knowledge in statistics. It measures skills in
data summarization, probability, inference, and decision-making. The multiple-choice and
scenario-based structure emphasizes real-world application, ethical practice, and critical thinking.
Candidates must interpret results, select appropriate methods, and justify conclusions using
statistical reasoning and professional standards.
SECTION ONE: QUESTIONS 1–100
1. Which of the following best defines statistics as a discipline?
A. The process of collecting, organizing, analyzing, interpreting, and presenting data
B. The process of graphing data only
C. The process of proving causation without evidence
D. The process of calculating probabilities only
🟢 A. The process of collecting, organizing, analyzing, interpreting, and presenting data
🔴 RATIONALE: Statistics is a comprehensive discipline that includes collecting, organizing,
analyzing, interpreting, and presenting data to support informed decisions.
2. A researcher measures the mean income of all households in a city. This value is an example of
which of the following?
A. Sample statistic
B. Sampling frame
C. Population parameter
D. Standard error
,🟢 C. Population parameter
🔴 RATIONALE: A population parameter is a numerical summary of an entire population, such as
the mean income of all households in a city.
3. A nurse manager uses hospital data to summarize the average length of stay for patients last
month. This is an example of which branch of statistics?
A. Inferential statistics
B. Descriptive statistics
C. Probability sampling
D. Hypothesis testing
🟢 B. Descriptive statistics
🔴 RATIONALE: Descriptive statistics summarize or describe the characteristics of a data set
without making inferences beyond the observed data.
4. A researcher records patient blood types as A, B, AB, and O. Which level of measurement is
being used?
A. Ordinal
B. Interval
C. Ratio
D. Nominal
🟢 D. Nominal
🔴 RATIONALE: Nominal measurement classifies data into categories with no inherent order.
, Blood type is a categorical variable with no ranking.
5. A pain scale classifies pain as mild, moderate, or severe. Which level of measurement is this?
A. Nominal
B. Ordinal
C. Interval
D. Ratio
🟢 B. Ordinal
🔴 RATIONALE: Ordinal measurement involves categories that have a meaningful order or
ranking, but the intervals between ranks may not be equal.
6. Temperature measured in degrees Celsius is an example of which level of measurement?
A. Interval
B. Nominal
C. Ordinal
D. Ratio
🟢 A. Interval
🔴 RATIONALE: Interval measurement has ordered values with equal intervals, but zero is
arbitrary and does not indicate absence of the variable.
7. Which level of measurement has a true zero and allows meaningful ratios?
