Learning ObjectivesConcept Map

after the completion of this module, the student will be able to

  • define and discuss the concepts of sensitivity and specificity in the context of diagnostic medical tests
  • false positive and false negative
  • define and produce a receiver operating curve and discuss its role in assessing
    how well a test can discriminate between categories

Knowledge and Skills

  • produce graphs in EXCEL (scatter plot)
  • calculate the likelihood of a patient having a disease based on the outcome of
    the result of a diagnostic medical test with given sensitivity and specificity and
    prevalence of the disease in the general population
  • calculate sensitivity and specificity based on a data set, graph the corresponding receiver operating curve (ROC)
  • interpret ROC and AUC


  • frequency interpretation of probability
  • conditional probability and Bayes Theorem
