Important Concepts in Quality Control: Specificity

Specificity Example: Calculations (1)

  • Determining the specificity of the experimental method will help show if the test is worthwhile.
  • Using the equation for specificity, we insert the following numbers:
    100 True Negatives
    Divided by (100 True Negatives + 275 False Positives)
    Times 100
    or
    (100 ÷ (100 + 275)) x 100.
  • The specificity for the “Experimental” method is 26.6%.
