Specificity Example: Test Results

  • In the pool of 1,000 samples, 600 were known positives.
  • The experimental method detected 875 positives, of which 275 were false. Of the 125 negatives detected by the experimental method, 25 were false.
  • The current method (Tried-and-True) detected only 625 positives, 25 of them false. 375 negatives were found as well, of which 50 were false-negatives.
  • The experimental method detected far more positives, but a great number of these were false. The current method, however, did generate more false-negatives than the experimental method.
