Test Bank For Biostatistics for the Biological and Health Sciences 2nd Edition By Marc M. Triola; Mario F. Triola; Jason Roy |All Chapters Inclusive |Updated 2026 Latest 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. G. 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 Rationale: Systematic sampling involves selecting every nth member of a population. 13. A researcher randomly selects 20 patients from each department in a hospital. What type of sampling is this? • A. Simple random sampling • B. Systematic sampling • C. Stratified sampling • D. Cluster sampling Answer: C Rationale: Stratified sampling involves dividing the population into subgroups (departments) and sampling within those groups. 14. In an experiment, the group that does not receive the treatment is known as the: • A. Experimental group • B. Control group • C. Independent variable • D. Dependent variable Answer: B Rationale: The control group is the group that does not receive the treatment and is used for comparison. 15. In an experiment, researchers study the effect of a new drug on blood pressure. The blood pressure is the: • A. Independent variable • B. Dependent variable • C. Control group • D. Experimental group Answer: B Rationale: The blood pressure is the dependent variable because it is the outcome being measured.
