The X-bar R chart is used to monitor the process performance of continuous data. You can also use it to collect data from subgroups at set time periods. It is actually two plots to monitor the process mean and the process variation over time and is an example ofstatistical process control...
In {eq}\bar{X} {/eq}- and {eq}R {/eq}-charts, constants are predetermined values derived from statistical theory and are used to calculate the control limits of the charts. These constants depend on the sample ...
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 constants required to construct E { X } and R charts for the λ-family are computed. Control charts based on the assumption of normality give inaccurate results when the tails of the underlying distribution are thin or thick. The validity of the normality assumption is examined by using ...

In alleviating the problem, this study has developed a new X-bar control chart for monitoring of process mean using skewness correction (SC) method for skewed distributions, thus named as SCS X control chart. The SC method is incorporated into the standard Shewhart's X-bar ...
