,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
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
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
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.
6. Which type of data is temperature in Celsius?
A. Nominal
B. Ordinal
C. Interval
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.
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
Rationale: The number of days is ratio data because it has a true zero and
meaningful differences between values.
10. A researcher categorizes patients by blood type. What level of measurement is this?
A. Nominal
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
Answer: D
Rationale: Age is ratio data because it has a true zero point and meaningful
differences between values.
12. Determine the type of sampling used: A hospital administrator selects every 5th patient from
a list of discharged patients.
A. Simple random sampling
B. Systematic sampling
C. Stratified sampling
D. Cluster sampling
Answer: B
