,1. Multiple Choice: What is the primary purpose of a case-
control study in epidemiology?
A) To determine the prevalence of a disease
B) To evaluate the effectiveness of a treatment
C) To identify factors that may contribute to a disease's
development
D) To establish the incidence rate of a disease
Correct Answer: C) To identify factors that may contribute
to a disease's development.
Rationale: Case-control studies are observational and
retrospective, focusing on comparing subjects with a
disease (cases) to those without (controls) to identify
potential causes or risk factors.
2. Fill-in-the-Blank: The measure of disease frequency over
a specified period among individuals who are at risk of
developing the disease is known as ____________.
Correct Answer: Incidence
Rationale: Incidence refers to the number of new cases of
a disease that occur in a specified population within a
certain time frame.
3. True/False: The cohort study design is the best option for
investigating rare diseases.
Correct Answer: False
Rationale: Cohort studies are not typically used for rare
diseases due to the large number of participants needed to
observe a sufficient number of cases.
4. Multiple Response: Which of the following are common
biases found in epidemiological studies? (Select all that

, apply)
A) Selection bias
B) Information bias
C) Confounding
D) Recall bias
Correct Answers: A) Selection bias, B) Information bias,
C) Confounding, D) Recall bias
Rationale: These biases can affect the validity of a study's
findings by influencing the selection of participants, the
accuracy of information collected, or the interpretation of
relationships between variables.
5. True/False: Randomization in a clinical trial eliminates
the possibility of confounding.
Correct Answer: False
Rationale: While randomization reduces the risk of
confounding, it does not completely eliminate it as there
may still be unknown or unmeasured factors that could
influence the outcome.
6. Multiple Choice: In epidemiology, the term 'endemic'
refers to:
A) A disease that is present continuously in a population
B) A rapidly increasing incidence of a disease
C) A disease that affects a large number of people
worldwide
D) A new, emerging disease
Correct Answer: A) A disease that is present
continuously in a population.
Rationale: An endemic disease is one that is consistently
present but limited to a particular region.
7. Fill-in-the-Blank: The statistical association between a
