Explanation
Factors are the process inputs (variables) that experimenters intentionally change to observe their effect on outputs - this is the foundational concept behind Design of Experiments (DOE).
Why the distractors are wrong:
- B. Hypothesis Testing is a statistical method for determining if observed differences are significant, not a term for inputs themselves.
- C. Control Plan is a document outlining how to monitor and control process variables after improvement - it's an output of the improvement process, not an input type.
- D. Population refers to the entire set of data or items being studied, not to manipulable process inputs.
Memory tip: Think of Factors as the Fiddler's knobs - the things you Flip or adjust during an experiment to see what changes. If you're in a lab and you can twist it, it's a Factor.
