1. Determine whether the given value is a statistic or a parameter: The average (mean) weight of all
x x x x x x x x x x x x x x x x


newborns in a hospital over a month is 7.5 pounds.
x x x x x x x x x x




• A. Statistic
x




• B. Parameter
x




xAnswer: B x




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 that
x x x x x x x x x x x x x x x x x


60% were satisfied with their healthcare.

• B. Parameter
x




xAnswer: A x




Rationale: The value is based on a sample, making it a statistic.

5. A researcher measures the height of patients in a clinic. What level of measurement is height?
x x x x x x x x x x x x x x x




• A. Nominal
x




• B. Ordinal
x




• C. Interval
x




• D. Ratio
x




xAnswer: D x




Rationale: Height is measured on a ratio scale because it has a true zero and meaningful differences
x x x x x x x x x x x x x x x x


between values.

6. Which type of data is temperature in Celsius?
x x x x x x x




• A. Nominal
x




• B. Ordinal
x




• C. Interval
x




• D. Ratio
x




xAnswer: C x




Rationale: Temperature in Celsius is interval data because it has no true zero, but the differences between
x x x x x x x x x x x x x x x x


values are meaningful.

• A. Discrete
x




• B. Continuous
x




xAnswer: B x




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 measurement
x x x x x x x x x x x x x x x x x


is this?
x x




• A. Nominal
x




• B. Ordinal
x




• C. Interval
x




• D. Ratiox




xAnswer: D x




Rationale: The number of days is ratio data because it has a true zero and meaningful differences between
x x x x x x x x x x x x x x x x x


values.

10. A researcher categorizes patients by blood type. What level of measurement is this?
x x x x x x x x x x x x




• A. Nominal
x




• B. Ordinal
x




• C. Interval
x




• D. Ratiox




xAnswer: A x




Rationale: Blood type is nominal data because it represents categories without a meaningful order.
