A process should be in control to assess the process capability. Control Charts are to detect special causes (non-random) of variation that may or may not be within the Control Limits. Every process will have random inherent (common cause) variation.

Variable data comes from measurements on a continuous scale, such as: temperature, time, distance, weight.
