Natural variations
A) are variations that are to be identified and investigated

C) are the same as assignable variations
D) lead to occasional False findings that processes are out of control
E) play no role in statistical process control

Question

Quizplus · Accepted Answer

Natural variations are inherent in any process and cannot be eliminated completely. As a result, there may be occasional false findings that the process is out of control when it is actually operating within expected natural variations. This is a common challenge in statistical process control. Option A is partially correct but does not capture the fact that natural variations are always present. Option B is incorrect as natural variations are not typically traced to a specific cause. Option C is incorrect as assignable variations are different from natural variations. Option E is incorrect as natural variations have an important role in statistical process control, as they help determine control limits for the process.
