A graph showing the relationship between two variable but interdependent quantities.
 Example sentencesExamples
-  Data were pooled to produce summary receiver operating characteristic curves and summary likelihood ratios for positive and negative test results.
 -  Sensitivity and specificity for the predictors were calculated, and receiver operator characteristic curves constructed.
 -  Receiver operator characteristic curves are in common use in laboratories.
 -  Diagnostic accuracy in this context has sometimes been defined with receiver operating characteristic curves and quantified by the area under the curve.
 -  If you plot a characteristic curve of the step wedges you will find quite simply that long wavelength light gives a greater gamma than light of short wavelength.
