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
Fr
• B. All patients admitted to a hospital in 2023
•
an
C. A group of patients selected for a study
• D. 50 diabetic patients from a clinic
kl
Answer: B
yn
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
pl
• B. Continuous
us
• C. Nominal
Pa

, Franklyn A Plus Pass
• 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
Fr
• D. Ratio
an
Answer: C
Rationale: Temperature in Celsius is interval data because it has no true zero, but the differences between
kl
values are meaningful.
yn
e
7. Determine whether the data is discrete or continuous: The number of babies born in a hospital each
day.
A
• A. Discrete
pl
• B. Continuous
us
Answer: A
Rationale: The number of babies born is discrete because it represents countable whole numbers.
