X bar R Control Chart – iSixSigma
X bar R Chart Formulas The X bar R chart can help you evaluate the stability of processes using variable data--time, cost, length, weight when you have 2 to 10 samples per period. Here are the X bar R chart formulas used in QI Macros for both the Range and Average (Xbar) charts:... Let’s look at the following example, for an X-bar chart, that will explain how we derive the A2 constant. The Generalize Control Limit Equation for Variable Charting The expression used to compute the control limits for an X-bar chart is:

X-bar chart and Special Cause If the R-chart is in control, i.e., stable and predictable, then any shifts in the mean of the process come from Special Cause. If the X-bar chart indicates the process is “out of control”, i.e., that Special Cause is present....
X-bar and range chart formulas. X-bar control limits are based on either range or sigma, depending on which chart it is paired with. When the X-bar chart is paired with a range chart, the most common (and recommended) method of computing control limits based on 3 standard deviations is: X-bar . n is the number of observations
