An I-chart is a type of control chart used to monitor the process mean when measuring individuals at regular intervals from a process. It is typical to use individual observations instead of rational subgroups when there is no basis for forming subgroups, when there is a long interval between observations becoming available, when testing is destructive or expensive, or for many other reasons. In statistical process control (SPC) charting, we use the A2 and E2 constants to calculate control limits for an Average (X-bar chart) and Individuals charts. But where do the A2 and E2 constants come from? Let's look at the following example, for an X-bar chart, that will explain how we derive the A2 constant.
