Individuals & Moving Range (ImR - XmR) Chart in Excel

Use an Individual Moving Range chart to evaluate stability of processes using variable data--time, cost, length, weight when your sample size is one.

Example of an Individual Moving Range chart created using the QI Macros for Excel.

The Individuals Moving Range (XmR) chart can help you evaluate a process when there is only one sample and they are farther apart: (i.e. monthly postage expense, time to write a computer program, etc).

Evaluate the range chart first. If it is "out of control," so is the process. If the range chart looks okay, then evaluate the X chart.
