The area under the receiver operating characteristic (ROC) curve is another diagnostic accuracy measurement, complementary to the sensitivity and specificity [4].For example, let’s say your thermometer was a degree off.It would be reliable (giving you the same results each time) but not valid (because the thermometer wasn’t recording the correct temperature).It is the proportion of variance in observed scores (i.e.scores on the test) attributable to true scores (the theoretical “real” score that a person would get if a perfect test existed).
