The R-chart, also known as the Range chart, is the most appropriate control chart for tracking variability in a process. This chart measures the range between the largest and smallest values in a sample and is useful for ensuring consistent quality in the filling of 12 oz. cans of beer. The x-bar chart would be used to track the mean or average of the filling process, while the p-chart and c-chart are used for measuring proportions and counts of nonconforming items respectively, and would not be appropriate for this scenario.
