Answer

Brief Explanations:

An X - bar chart is a type of control chart used in statistical process control. It plots the sample means over time. The central tendency of a process output is measured by the mean. So, an X - bar chart is used to detect changes in the central tendency of the process output.

Answer:

Change in the central tendency of the process output
