Author: Paul Baum Last modified by: Paul Baum Created The x-bar and R-chart are quality control charts used to monitor the mean and variation of a process based on samples taken in a given time. The control limits on both chats are used to monitor the mean and variation of the process going forward. The Xbar and R chart is a common SPC control chart. In this article, learn everything you need to know about the xbar and r chart. The Control Chart Template above works for the most common types of control charts: the X-Bar chart (plotting the mean of a sample over time), the R chart (plotting the range or Max-Min of a sample over time), and the s chart (plotting the sample standard deviation over time).
