This is the difference between the rate of disease in the nonexposed segment of the population and the overall rate in the population.
Is designed to test preventive measures
These are a form of intervention studies, two types are randomized controlled trials and quasiexperiments

Where the investigator manipulates the study factor but does not assign individual subjects randomly to the exposed and non-exposed groups.

When sensitivity tests correctly identify all potential cases as either negative or positive
It helps to generalize the study to the population
The standard will help to conclude that the results were true
When sensitivity tests correctly identify all potential cases as either negative or positive
This is the generalizing of the study to the population
Was the conclusion true? It is the extent to which you can believe your results
It is the third variable that relates to the exposure and the outcome
