Quizplus · Accepted Answer

Common or chance causes refer to the inherent variability that is present in any system of operation. These causes are part of the natural variability of the system and cannot be eliminated. Special or assignable causes, on the other hand, are not part of the natural variability of the system and can be identified and eliminated. Explained variation refers to the portion of the total variability in a system that can be explained by specific factors or variables. The standard deviation is a measure of the dispersion or spread of a set of data values.
