An xbar control chart is used to monitor the central tendency or average of a process. It is the most suitable choice when the quality of a process's output is determined by the average value of a sample. The xbar control chart plots the sample averages against the center line, which represents the overall average of the process. The upper and lower control limits are also plotted, which helps in determining when the process is out of control. Any points beyond the control limits would indicate that the process is going out of control and needs to be inspected or adjusted. Therefore, an xbar control chart is the best choice for monitoring the average value of the sample to ensure that the process is in control and producing quality output.
