Mortality rate

Case-control ratio

What is the purpose of a case-control study in epidemiology?

To determine the cause of a disease

To calculate the prevalence of a disease

To study the natural history of a disease

To compare individuals with and without a disease

What is the difference between incidence and prevalence?

Incidence is the number of new cases in a population, while prevalence is the total number of cases.

Incidence is the total number of cases, while prevalence is the number of new cases.

Incidence is the number of cases at a specific point in time, while prevalence is the number of cases over a period.

Incidence is the number of cases over a period, while prevalence is the number of cases at a specific point in time.

Which of the following is a measure of association in epidemiology?

Prevalence ratio

Confidence interval

P-value

Standard deviation

What is the role of a control group in an epidemiological study?

To provide baseline data for comparison

To ensure all participants receive the same treatment

What is the difference between a pandemic and an epidemic?

A pandemic is more severe than an epidemic.

A pandemic affects a larger geographic area than an epidemic.

A pandemic is caused by a virus, while an epidemic is caused by bacteria.

There is no difference between a pandemic and an epidemic.
