WebAssuming an assignable cause is found, remove the out-of-control point (sample 15) and re-calculate control limits. Removing the sample from calculation (in Minitab, X-bar-R Chart options > Estimate > Omit the following subgroups), the new control limits are: (b) Estimate the process standard deviation. ˆ x Rd / 2 0 / 1 0 Web27 mrt. 2024 · Step 4: Plot Data Points and Identify Out-Of-Control Data Points. After establishing control limits, the next step is to plot the data points on the SPC chart. Once you’ve plotted the data points, you can start to see patterns in them. Recognizing these patterns is the key to finding the root cause of special causes.
