What is an R Chart?

An R Chart, also known as a Range Chart, is a statistical tool used to monitor the variability of a process over time. It is commonly used in quality control and process improvement to identify any patterns or trends in data that may indicate a need for intervention. The R Chart is created by plotting the range of data points within a subgroup against the subgroup number or time period. This allows analysts to quickly identify any outliers or shifts in the process that may be affecting product quality.
