Specificity, and how to calculate? - ANSWER -Ability of a test to identify normality, or
how many results were correctly called negative.
, # of true negative divided by # of all negative tests by gold standard, or TN/TN+FP
Positive predictive value, and how to calculate? - ANSWER -percentage of test results
that accurately predict abnormality, or what % correctly predicted disease.
- # of true positive test divided by # of all positive tests, or TP/TP+FP
Negative predictive value, and how to calculate? - ANSWER - % of test results that
correctly predict normality, or what % correctly predicted absence of disease.
- # of true negatives divided by # of all negative tests, or TN/TN+FN
Accuracy, and how to calculate? - ANSWER - % of correct tests, or how well does the
test both detect and rule out disease.
- total # of correct tests divided by total # of all tests, or TP+TN/TP+FP+FN+TN
