Chapter 1: General Overview (Questions 1–100)
1. What is the primary goal of biostatistics?
a) To collect data without analysis
b) To apply statistical methods to analyze data in biological and medical research
c) To design laboratory equipment
d) To perform clinical surgeries
b) To apply statistical methods to analyze data in biological and medical
research
Rationale: Biostatistics integrates statistical principles with biological and
medical contexts to draw valid conclusions from research data, supporting
evidence-based decision-making in health sciences.
2. What is a population in biostatistics?
a) A subset of individuals selected for a study
b) The complete set of measurements or individuals of interest
c) A single measurement from an experiment
d) A group of researchers
b) The complete set of measurements or individuals of interest
Rationale: The population includes all possible observations relevant to a
research question, from which a sample is drawn for practical study.
3. What is a sample?
a) The entire group under study
b) A subset of the population selected for analysis
c) A type of statistical test
d) A measure of disease frequency
b) A subset of the population selected for analysis
Rationale: Samples are smaller, manageable subsets used to estimate
population parameters because studying entire populations is often impractical.
4. What is a parameter?
a) A numerical summary of sample data
b) A numerical summary of a population
c) A type of study design
d) A measure of variability
, 4|Page
b) A numerical summary of a population
Rationale: Parameters describe fixed but often unknown population
characteristics, such as the true mean or proportion.
5. What is a statistic?
a) A numerical summary of a population
b) A numerical summary of a sample
c) A type of bias
d) A clinical trial phase
b) A numerical summary of a sample
Rationale: Statistics are calculated from sample data and used to estimate
unknown population parameters.
6. Which study design looks backward in time?
a) Prospective cohort study
b) Retrospective case-control study
c) Randomized controlled trial
d) Cross-sectional study
b) Retrospective case-control study
Rationale: Retrospective studies examine past exposures or risk factors in
relation to current disease status.
7. Which study design follows participants forward in time?
a) Retrospective study
b) Prospective cohort study
c) Case report
d) Ecological study
b) Prospective cohort study
Rationale: Prospective studies track participants over time to observe incident
outcomes and establish temporal associations.
8. What distinguishes an experiment from an observational study?
a) Experiments do not involve human subjects
b) Experiments actively assign treatments or interventions
c) Observational studies are always longitudinal
d) Experiments cannot be randomized
b) Experiments actively assign treatments or interventions
Rationale: Experimental designs, especially randomized controlled trials,
involve investigator-initiated interventions to assess causality.
9. What is incidence?
a) Total existing cases at a time point
b) New cases occurring over a specified period
c) Deaths due to disease
d) Disease severity score
b) New cases occurring over a specified period
Rationale: Incidence measures the rate of new disease onset, reflecting risk in
the population.
