An X-bar and R (range) chart is a pair of control charts used with processes that have a subgroup size of two or more. The standard chart for variables data, X-. The X-Bar chart shows how much variation exists in the process over time. • The Range (R) chart shows the variation within each variable (called "subgroups"). A. The basic difference is that X bar S charts plot the subgroup standard deviation, whereas R charts plot the subgroup range. Selection of an appropriate control. XBar-R Chart. The XBar-R pair of charts are the most commonly used charts in SPC. You will find the chart listed under may different names, including: XBar-R.
