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