Nettet7. nov. 2024 · For the Individuals Chart, the limits are three standard deviations away from the centerline, and the standard deviation is calculated by taking the average moving range and dividing by an unbiasing constant. For the Moving Range Chart, the limits are a multiple of the average moving range. 2. NettetThe overall average ( X) and the average moving range ( R) are then calculated using the following formulas: X = ΣX/k. R = ΣR/ (k-1) where k = number of samples. Now you can calculate the upper control limit (UCLx) and lower control limit (LCLx) for the X chart as follows: UCLx = X + 2.66 R. LCLx = X - 2.66 R.
