March 2005 In this issue: Introduction to X-R Charts Example When to Use X-R Charts Steps in Constructing an X-R Chart Summary Quick Links This month is the first in a multi-part publication on X-R charts. For bigger samples, the s-chart must be used instead to monitor the standard deviation of the sample rather than its range. X Bar: The x-bar is used to represent the sample mean; that is, the mean of a sample rather than an entire population. Each point on the chart acts as a subgroup mean value. An R chart is used to monitor _____. The mean of the entire population is usually represented by the Greek letter mu. X Bar Control Chart: The X-bar chart is a control chart that is used to monitor the arithmetic means of samples of constant size, n. Control charts are used to analyze variation within processes. If the subgroup size is between 7 and 10, select the appropriate constant, called D3, and multiply by R-bar to determine the Lower Control Limit for This on-line psychrometric calculator makes air property determination simple. Process: Calculate, plot, and evaluate the Range Chart first. multiply by R-bar to determine the Upper Control Limit for the Range Chart.

The \(R\) chart \(R\) control charts: This chart controls the process variability since the sample range is related to the process standard deviation. Once you decide to monitor a process and after you determine using an $- \bar{X} -$ & R chart is appropriate, you have to construct the charts.
