1. Determine whether the given value is a statistic or a parameter: The average (mean) weight of
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
all newborns in a hospital over a month is 7.5 pounds.
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
• A. Statistic
p4
• B. Parameter
p4
p4 Answer: B p4
Rationale: Since it refers to the entire population of newborns in the hospital, it is a parameter.
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
2. Determine whether the given value is a statistic or a parameter: A survey of 100 patients found
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
that 60% were satisfied with their healthcare.
p4 p4 p4 p4 p4 p4 p4
• A. Statistic
p4
• B. Parameter
p4
p4 Answer: A p4
Rationale: The value is based on a sample, making it a statistic.
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
3. Which of the following represents a population?
p4 p4 p4 p4 p4 p4
• A. A sample of 200 patients from a hospital
p4 p4 p4 p4 p4 p4 p4 p4
• B. All patients admitted to a hospital in 2023
p4 p4 p4 p4 p4 p4 p4 p4
• C. A group of patients selected for a study
p4 p4 p4 p4 p4 p4 p4 p4
• D. 50 diabetic patients from a clinic
p4 p4 p4 p4 p4 p4
p4 Answer: B p4
Rationale: A population includes all members of a group, while a sample is a subset of the population.

4. A nurse records the number of times each patient visits the clinic in a month. What type of data is this?
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
• A. Discrete
p4
• B. Continuous
p4
• C. Nominal
p4

p4 p4
,• D. Ordinal
p4
p4 Answer: A p4
Rationale: The number of visits is discrete data because it represents countable whole numbers.
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
5. A researcher measures the height of patients in a clinic. What level of measurement is height?
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
• A. Nominal
p4
• B. Ordinal
p4
• C. Interval
p4
• D. Ratio
p4
p4 Answer: D p4
Rationale: Height is measured on a ratio scale because it has a true zero and meaningful differences
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
between values.
p4 p4
6. Which type of data is temperature in Celsius?
p4 p4 p4 p4 p4 p4 p4
• A. Nominal
p4
• B. Ordinal
p4
• C. Interval
p4
• D. Ratio
p4
p4 Answer: C p4
Rationale: Temperature in Celsius is interval data because it has no true zero, but the differences between
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
values are meaningful.
p4 p4 p4
7. Determine whether the data is discrete or continuous: The number of babies born in a hospital
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
each day.
p4 p4
• A. Discrete
p4
• B. Continuous
p4
p4 Answer: A p4
Rationale: The number of babies born is discrete because it represents countable whole numbers.

, 8. Determine whether the data is discrete or continuous: The weight of each newborn in a hospital.
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
• A. Discrete
p4
• B. Continuous
p4
p4 Answer: B p4
Rationale: Weight is continuous data because it can take any value within a range.
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
9. A nurse collects data on the number of days patients spend in the hospital. What level of
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
measurement is this?
p4 p4 p4
• A. Nominalp4
• B. Ordinal
p4
• C. Interval
p4
• D. Ratio p4
p4 Answer: D p4
Rationale: The number of days is ratio data because it has a true zero and meaningful differences between
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
values.
p4
10. A researcher categorizes patients by blood type. What level of measurement is this?
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
• A. Nominalp4
• B. Ordinal
p4
• C. Interval
p4
• D. Ratio p4
p4 Answer: A p4
Rationale: Blood type is nominal data because it represents categories without a meaningful order.
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
11. In a study, the ages of participants are recorded. What type of variable is age?
p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4 p4
• A. Nominalp4
• B. Ordinal
