Question

The extent to which the score correctly excludes individuals with normal speech from the abnormal group:

A. Sensitivity
B. Specificity
C. Positive Predictive Value (PPV)
D. Negative Predictive Value (NPV)

Answer 1

The extent to which the score correctly excludes individuals with normal speech from the abnormal group is known as Specificity. If a test has high specificity, the probability of a false positive is low.

Step-by-step explanation:

The extent to which the score correctly excludes individuals with normal speech from the abnormal group is known as Specificity. Test specificity is the probability of getting a negative test result when the patient is not infected. If a test has high specificity, the probability of a false positive is low.

For example, if a speech evaluation test correctly identifies 90% of individuals with normal speech as being normal, we can say that the test has a specificity of 90%.
