The R chart (also known as the Range chart) is used to track sample ranges in a process control system. It helps identify any abnormal variation in the process and is commonly paired with the x-bar chart, which tracks the process mean. The p and c charts are used for tracking attribute data, while the R chart and x-bar chart are used for tracking continuous data.
