I-Mr Chart . The center line is the average of all moving ranges. When you change an unstable process, you can't accurately assess the effect of the changes.
I-Mr Chart - Six Sigma Study Guide from sixsigmastudyguide.com
The control limits on the i chart, which are set at a distance of 3 standard deviations above and below the center line, show the amount of variation that is expected in the individual sample values. These charts are used to verify process control before assessing capability such as cpk, ppk, cp, pp, or cpm. Determining whether a process is stable and ready to be improved.

Points that fail minitab's tests are marked with a red symbol on the mr chart. The moving range (mr) chart shows variability between one.
