1. Determine whether the given value is a statistic or a parameter: The average (mean) weight of a
+i +i +i +i +i +i +i +i +i +i +i +i +i +i +i +i
ll newborns in a hospital over a month is 7.5 pounds.
+i +i +i +i +i +i +i +i +i +i
• A. Statistic
+i
• B. Parameter
+i
Answer: B
+i +i
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 th
+i +i +i +i +i +i +i +i +i +i +i +i +i +i +i +i +i
at 60% were satisfied with their healthcare.
+i +i +i +i +i +i
• A. Statistic
+i
• B. Parameter
+i
Answer: A
+i +i
Rationale: The value is based on a sample, making it a statistic.

3. Which of the following represents a population?
+i +i +i +i +i +i
• A. A sample of 200 patients from a hospital
+i +i +i +i +i +i +i +i
• B. All patients admitted to a hospital in 2023
+i +i +i +i +i +i +i +i
• C. A group of patients selected for a study
+i +i +i +i +i +i +i +i
• D. 50 diabetic patients from a clinic
+i +i +i +i +i +i
Answer: B
+i +i
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?
+i +i +i +i +i +i +i +i +i +i +i +i +i +i +i +i +i +i +i +i
• A. Discrete
+i
• B. Continuous
+i
• C. Nominal
+i
Page | 3 +i +i
, • D. Ordinal
+i
Answer: A
+i +i
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?
+i +i +i +i +i +i +i +i +i +i +i +i +i +i +i
• A. Nominal
+i
• B. Ordinal
+i
• C. Interval
+i
• D. Ratio
+i
Answer: D
+i +i
Rationale: Height is measured on a ratio scale because it has a true zero and meaningful differences bet
+i +i +i +i +i +i +i +i +i +i +i +i +i +i +i +i +i
ween values. +i
6. Which type of data is temperature in Celsius?
+i +i +i +i +i +i +i
• A. Nominal
+i
• B. Ordinal
+i
• C. Interval
+i
• D. Ratio
+i
Answer: C
+i +i
Rationale: Temperature in Celsius is interval data because it has no true zero, but the differences between val
+i +i +i +i +i +i +i +i +i +i +i +i +i +i +i +i +i
ues are meaningful.

7. Determine whether the data is discrete or continuous: The number of babies born in a hospital ea
+i +i +i +i +i +i +i +i +i +i +i +i +i +i +i +i
ch day.
+i
• A. Discrete
+i
• B. Continuous
