Control chart analysis helps the QI project team identify and using control charts to analyze and manage Minitab Statistical Software, Minitab, State Col-. I ran a basic test on some random data. I created a random set of 150 data points, and ran an IMR chart for it, so I would have a point of A control chart indicates when your process is out of control and helps you identify the presence of special-cause variation. When special-cause variation is present, your process is not stable and corrective action is necessary. Control charts are graphs that plot your process data in time-ordered sequence.

A control chart indicates when your process is out of control and helps you identify the presence of special-cause variation. When special-cause variation is present, your process is not stable and corrective action is necessary. Control charts are graphs that plot your process data in time-ordered sequence. Rather than tossing out perfectly good data, you can create a subgroup indicator column to let Minitab know that the subgroup size varies. You can then enter this subgroup column in the Stat > Control Charts and Stat > Quality Tools > Capability Analysis dialog boxes. Note that you can use a subgroup indicator column for any of the cases above.

In Using the Laney P' Control Chart in Minitab Software Development, Dawn Keller discusses the distinction between P' charts and their cousins, described by Tammy Serensits in P When you have a large number of subgroups or observations, consider splitting your control chart into segments for easier interpretation. If your chart has stages, Minitab calculates separate control limits and center line estimates for each segment. This control chart is split into two segments, by stage. But if you're using Minitab Statistical Software, you can choose Assistant > Control Charts and get step-by-step guidance through the process of creating a control chart, from determining what type of data you have, to making sure that your data meets necessary assumptions, to interpreting the results of your chart. Minitab control charts also display a center line and control limits. The center line is the average value of the quality statistic that you choose to assess. If a process is in control, the points will vary randomly around the center line. Putting Control Charts on the Stage The best choice in a case like this is to create a control chart in “stages,” which is easy to do with a statistical software package such as Minitab. Stages are used to create a historical control charts that shows how a process changes over specific time periods. If the MR chart is in control, you can be sure that an out-of-control I chart is due to changes in the process center. Points that fail Minitab's tests are marked with a red symbol on the MR chart. In this MR chart, the lower and upper control limits are 0 and 0.4983, and none of the individual observations fall outside those limits.The points also display a random pattern.
