, Chapter 1: Introduction to Statistics
1. Determine whether the given value is a statistic or a parameter: The average (mean) weight of all
newborns in a hospital over a month is 7.5 pounds.
• A. Statistic
• B. Parameter
Answer>> B
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 60% were satisfied with their healthcare.
• A. Statistic
• B. Parameter
Answer>> A
Ar
Rationale: The value is based on a sample, making it a statistic.
ch
3. Which of the following represents a population?
Do
• A. A sample of 200 patients from a hospital
•
c
B. All patients admitted to a hospital in 2023
• C. A group of patients selected for a study
• D. 50 diabetic patients from a clinic
Answer>> B
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?
• A. Discrete
• B. Continuous
• C. Nominal
2
,• D. Ordinal
Answer>> A
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
• D. Ratio
Answer>> D
Rationale: Height is measured on a ratio scale because it has a true zero and meaningful differences
between values.
Ar
6. Which type of data is temperature in Celsius?
ch
• A. Nominal
• B. Ordinal
Do
• C. Interval
c
• D. Ratio
Answer>> C
Rationale: Temperature in Celsius is interval data because it has no true zero, but the differences
between 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.
3
, 8. Determine whether the data is discrete or continuous: The weight of each newborn in a hospital.
• A. Discrete
• B. Continuous
Answer>> B
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 is this?
• A. Nominal
• B. Ordinal
• C. Interval
• D. Ratio
Answer>> D
Ar
Rationale: The number of days is ratio data because it has a true zero and meaningful differences
ch
between values.
Do
10. A researcher categorizes patients by blood type. What level of measurement is this?
• A. Nominal
c
• B. Ordinal
• C. Interval
• D. Ratio
Answer>> A
Rationale: Blood type is nominal data because it represents categories without a meaningful order.
11. In a study, the ages of participants are recorded. What type of variable is age?
• A. Nominal
• B. Ordinal
• C. Interval
• D. Ratio
