CHAPTER 1: INTRODUCTION TO BIOSTATISTICS
# Foundational Concepts & Definitions
Q1. What is the definition of a population in biostatistics?
A) A subset of measurements from a larger group
1
,B) The complete set of measurements of interest
C) A sample selected randomly from a larger group
D) Any group of individuals studied in research
☑ ANSWER: B
RATIONALE: A population is the entire set of measurements or observations of
interest in a study. It includes all individuals or objects that share a common
characteristic . A sample is a subset of the population.
Q2. Which of the following best defines a sample?
A) The entire group of individuals being studied
B) A subset of the population, usually representative
C) All possible measurements that could be taken
D) The final results of a statistical analysis
☑ ANSWER: B
2
,RATIONALE: A sample is a subset of the population selected to represent the
larger group. Samples are used in statistical inference to draw conclusions about
populations .
Q3. What is the primary role of a statistician in research?
A) Only to collect data
B) To analyze data and make inferences about populations based on sample data
C) To determine the research hypothesis
D) To write the research paper
☑ ANSWER: B
RATIONALE: Statisticians analyze data and make inferences about populations
based on sample data. They guide the design of experiments, estimate sample
sizes, and interpret results .
Q4. What is the difference between descriptive and inferential statistics?
3
, A) Descriptive statistics draw conclusions; inferential statistics organize data
B) Descriptive statistics organize and summarize data; inferential statistics make
conclusions about populations
C) They are the same concept
D) Descriptive statistics are only used in experiments
☑ ANSWER: B
RATIONALE: Descriptive statistics organize and summarize data through tables,
graphs, and basic computations. Inferential statistics make conclusions about
populations based on sample data .
Q5. Which sampling method gives every member of the population an equal
chance of being selected?
A) Convenience sampling
B) Systematic sampling
C) Simple random sampling
D) Quota sampling
☑ ANSWER: C
