This is one of a set of measures used to assess the accuracy of a diagnostic test (see sensitivity, negative predictive value and positive predictive value). Specificity is the proportion of people without a disease who are correctly identified as not having that disease by the diagnostic test. For example, if a test has a specificity of 95%, this means that it correctly identified 95% of the people who did not have the disease, but that 5% of people without the disease were incorrectly diagnosed as having the disease (these people were ‘false positives’ on the test).
A few days later, Tony Taylor was sentenced. Since Taylor had been the first co-conspirator to plead guilty and had provided investigators with details of the dogfighting operation, the prosecutor had recommended that Taylor only serve probation. However, the judge said it wouldn’t be fair to give Taylor probation after sentencing his co-defendants to 18 months or more in prison. He told Taylor, “You were as much an abuser of animals as any other defendant in this case.” The judge sentenced Taylor to 2 months in prison.
