Input interpretation
negative predictive value
Equation
npv = tn/(tn + fn) | npv | negative predictive value tn | true negatives fn | false negatives
Input values
true negatives | 22 false negatives | 2
Results
negative predictive value | 0.9167
Possible intermediate steps
Calculate the negative predictive value using the following information: known variables | | tn | true negatives | 22 fn | false negatives | 2 The relevant equation that relates negative predictive value (npv), true negatives (tn), and false negatives (fn) is: npv = tn/(tn + fn) Substitute known variables into the equation: known variables | | tn | true negatives | 22 fn | false negatives | 2 | : npv = 22/(22 + 2) Evaluate 22/(22 + 2): Answer: | | npv = 0.9167
