Quizplus · Accepted Answer

A mixture is difficult to identify because it involves varying patterns of data that don't fit a single control chart pattern. It could include multiple sources of variation and require more advanced statistical analysis to identify and address. Oscillation, cycle, and trend all have more distinct patterns that can be identified on a control chart.
