A p chart is used to monitor the proportion of defective units in a production process. It is an effective tool to determine if a process is stable and consistent or if there are variations that need to be addressed to improve quality control. The chart plots the proportion of defective items in a subgroup against the sample size, allowing for easy identification of any patterns or trends that may indicate a problem with the process. Therefore, the best choice for a control chart used when the output of a production process is measured in terms of the proportion defective is a p chart.
