Question

Quizplus · Accepted Answer

A c-chart is appropriate for monitoring the count of defects in a sample of items, where each item can have more than one defect. In this case, the Plexiglass panels can have multiple scratches, making a c-chart the most appropriate control chart to use. The other options are not suitable for this type of data. The $ \bar{x} $ chart is used for continuous data, a p-chart is used for binary data, and an R-chart is used for measuring the range or variation in continuous data.
