Input interpretation
specificity calculation
Equation
spec = tn/(tn + fp) | spec | specificity fp | false positives tn | true negatives
Input values
false positives | 3 true negatives | 18
Results
specificity | 0.8571
Possible intermediate steps
Calculate the specificity using the following information: known variables | | fp | false positives | 3 tn | true negatives | 18 The relevant equation that relates specificity (spec), false positives (fp), and true negatives (tn) is: spec = tn/(tn + fp) Substitute known variables into the equation: known variables | | fp | false positives | 3 tn | true negatives | 18 | : spec = 18/(18 + 3) Evaluate 18/(18 + 3): Answer: | | spec = 0.8571
