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
CORRECT 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
CORRECT ANSWER: A
Rationale: The value is based on a sample, making it a statistic.
3. Which of the following represents a population?
A. A sample of 200 patients from a hospital
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
CORRECT 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
D. Ordinal
CORRECT 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
CORRECT ANSWER: D
Rationale: Height is measured on a ratio scale because it has a true zero and meaningful
differences between values.
6. Which type of data is temperature in Celsius?
A. Nominal
B. Ordinal
C. Interval
D. Ratio
CORRECT 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
CORRECT ANSWER: A
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.
A. Discrete
B. Continuous
CORRECT 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
