Explanation

Common Cause Variation represents the natural, inherent fluctuation in any stable process due to random factors within the system itself. It creates the steady, random distribution of data points around the average that you'd expect in a stable process. Special Cause Variation is different - it's caused by identifiable, non-random factors that create assignable, unusual patterns.
