, 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 Ans: 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 Ans: 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 Ans: 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
Page | 3
, • D. Ordinal
Ans: 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
Ans: 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
Ans: 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 Ans: A
Rationale: The Number Of Babies Born Is Discrete Because It Represents Countable Whole Numbers.
