To correctly interpret an X-bar R chart, always examine the R chart first. The X bar chart controls limits derived from the R bar (average range) values. If the R chart’s values are out of control, the X bar chart control limits are inaccurate. If the points in the R chart are o...
Note that this chart, whilst the easiest to calculate and using fewer measures, also gives the least sensitive results and should only be used when limited measures are available. Fig. 1. Calculating X/MR control limits Next time:Calculation detail for X-bar/R Control Charts ...

The Specification Limits for X-bar Chart group allows you to specify fixed limits to be displayed on the chart along with the calculated limits. This can be useful if you want to determine whether a process falls within predetermined tolerance limits. ...

Average And Range - X-Bar and R: If the sample size is relatively small (e.g., less than 10-15), we can use the range instead of the standard deviation of a sample to construct control charts on X-Bar (arithmetic mean) and the range, R. The range of a sa

The X-bar chart is often used in conjunction with a variation chart such as the R-chart or s-chart. The average sample range, R, or the average sample standard deviation, s, can be used to derive the X-bar chart's control limits. 展开 DOI: doi:978-613-0-56691-3 ...
“Usually, the X-Bar Chart is combined with an R-Chart to inspect processes where data is not available frequently. The chart monitors variation in sample results over time and checks whether the process is in control.”-Sanket Saha, Process Manager. ...
