1. Determine whether the given value is a statistic or a parameter: The average (mean) weight of all
jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj
newborns in a hospital over a month is 7.5 pounds.
jj jj jj jj jj jj jj jj jj jj
• A. Statistic
jj
• B. Parameter
j
jj Answer: Bjj
Rationale: Since it refers to the entire population of newborns in the hospital, it is a parameter.

2. Determine whether the given value is a statistic or a parameter: A survey of 100 patients found
jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj
that 60% were satisfied with their healthcare.
jj jj jj jj jj jj jj
• A. Statistic
jj
• B. Parameter
j
jj Answer: Ajj
Rationale: The value is based on a sample, making it a statistic.

• D. 50 diabetic patients from a clinic
jj jj jj jj jj jj
jj Answer: Bjj
Rationale: A population includes all members of a group, while a sample is a subset of the population.

,• D. Ordinal
j
jj Answer: A jj
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?
jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj
• A. Nominal
jj
• B. Ordinal
jj
• C. Interval
jj
• D. Ratio
j
jj Answer: D jj
Rationale: Height is measured on a ratio scale because it has a true zero and meaningful differences
jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj
between values.

6. Which type of data is temperature in Celsius?
jj jj jj jj jj jj jj
• A. Nominal
jj
• B. Ordinal
jj
• C. Interval
jj
• D. Ratio
j
jj Answer: C jj
Rationale: Temperature in Celsius is interval data because it has no true zero, but the differences between
jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj
values are meaningful.

7. Determine whether the data is discrete or continuous: The number of babies born in a hospital
jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj
each day.
jj jj
• A. Discrete
jj
• B. Continuous
j
jj Answer: A jj
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.
jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj
• A. Discrete
jj
• B. Continuous
j
jj Answer: B jj
Rationale: Weight is continuous data because it can take any value within a range.

9. A nurse collects data on the number of days patients spend in the hospital. What level of
jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj
measurement is this?
jj jj jj
• A. Nominaljj
• B. Ordinaljj
• C. Interval
jj
• D. Ratio j
jj Answer: D jj
Rationale: The number of days is ratio data because it has a true zero and meaningful differences between
jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj jj
values.

10. A researcher categorizes patients by blood type. What level of measurement is this?
jj jj jj jj jj jj jj jj jj jj jj jj
• A. Nominaljj
• B. Ordinaljj
• C. Interval
jj
• D. Ratio j
jj Answer: A jj
Rationale: Blood type is nominal data because it represents categories without a meaningful order.
