many tests are correctly called positive.
- # of true positives divided by # of all positive tests by gold
standard, or TP/TP+FN
◉ 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: -
percentage of test results that accurately 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
