Question

__________________ arises from a single or small set of causes that are not part of event or process and therefore can be traced, identified and implemented or eliminated. In general, researchers are interested in this variation because they can link-or-assign variation to a single specific cause and act accordingly.

A. Process variation
B. Assignable variation
C. Random variation
D. Performance variation

Answer 1

Assignable variation arises from a specific, identifiable cause and can be managed or eliminated, unlike natural or random variation.

Step-by-step explanation:

The type of variation that arises from a single or small set of causes that are not part of an event or process and can be traced, identified, and managed is known as Assignable variation. Assignable variation is of particular interest to researchers and quality control professionals because it often indicates a problem with a process that can be corrected. It differs from natural or random variation which is inherent in a process and cannot be traced to a specific cause. For example, if a factory produces metal rods and there is sudden variability in the rod's thickness that can be traced back to a malfunctioning machine, this would be considered an example of assignable variation because the cause can be identified and fixed.
