Rationale: The number of visits is discrete data because it represents countable whole numbers.
5. A researcher measures the height of patients in a clinic. What level of measurement is height?
• A. Nominal
• B. Ordinal
• C. Interval
M
• D. Ratio
Answer: D
ED
Rationale: Height is measured on a ratio scale because it has a true zero and meaningful differences
between values.
ST
6. Which type of data is temperature in Celsius?
• A. Nominal
• B. Ordinal
•
U
C. Interval
• D. Ratio
D
Answer: C
Rationale: Temperature in Celsius is interval data because it has no true zero, but the differences between
Y
values are meaningful.
7. Determine whether the data is discrete or continuous: The number of babies born in a hospital each
day.
• A. Discrete
• B. Continuous
Answer: A
Rationale: The number of babies born is discrete because it represents countable whole numbers.
