Question

Quizplus · Accepted Answer

An ROC (receiver operating characteristic) curve is a graph plotting the trade-off between hits (correct detections) and false alarms (incorrect detections) in a signal detection task. Therefore, the correct choice is C, hits versus false alarms. Choice A represents a graph of hits versus misses, which do not take into account correct rejections, and choice B represents a graph of hits versus correct rejections, which do not take into account false alarms.
