X-bar and R Control Chart Issues and Resolution. X-bar and R control charts are used in quality control to identify when special cause or out-of-control conditions occur in time-series data so that timely corrective actions can be taken to resolve problems.
A bar graph is not the same as a histogram. On a histogram, the width of the bar varies according to the range of the x-axis variable (for example, 0-2, 3-10, 11-20, 20-40 and so on) and the area of the column indicates the frequency of the data. With a bar graph, it is only the height of the bar that matters.
