**predictive value is the**probability that subjects with a negative screening test truly don't have the disease.

Moreover, what is a positive value in math?

**Absolute Value**.

**Absolute value**describes the distance of a

**number**on the

**number**line from 0 without considering which direction from zero the

**number**lies. The

**absolute value**of a

**number**is never

**negative**.

How is positive predictive value calculated?

Specificity: probability that a test result will be negative when the disease is not present (true negative rate).

**Positive predictive value**: probability that the disease is present when the test is**positive**. = a / (a+c) Negative**predictive value**: probability that the disease is not present when the test is negative.What values are important to you?
