A control chart on which subgroup ranges are plotted versus time is called an R-chart. The R-chart is used to monitor process variability by tracking the range of subgroup measurements. This helps identify any unusual variation in the process and to take corrective action if needed. The other choices, $\overline { \mathrm { X } }$, p, and C charts, are used for monitoring the process mean, proportion defective, and count of defects or events, respectively.
