Quizplus · Accepted Answer

An operating characteristic (OC) curve shows the probability of accepting a lot for a given level of quality, which is represented by the percentage of defectives in the lot. It is commonly used in quality control to assess the effectiveness of a sampling plan. A power curve and np curve are not relevant to this scenario, and a control chart is a tool used for monitoring a process, not for assessing the quality of a lot.
