What is specificity?
Understand the Problem
The question asks for the definition of 'specificity.' In the context of science or medicine, specificity usually refers to the ability of a test to correctly identify those without the disease (true negative rate).
Answer
Specificity measures a test's ability to correctly identify those without a disease (true negatives).
Specificity measures how well a test correctly identifies individuals without a specific disease, indicating the test's ability to produce true negative results.
Answer for screen readers
Specificity measures how well a test correctly identifies individuals without a specific disease, indicating the test's ability to produce true negative results.
More Information
Specificity is often used with sensitivity to evaluate the accuracy of diagnostic tests. A high specificity means fewer false positives.
Tips
A common mistake is confusing sensitivity with specificity. Sensitivity measures true positives, while specificity measures true negatives.
