,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 any49value49within49a49range.
