In a gauge R&R study, what does reproducibility measure?

• A. Variation between operators.
• B. Variation within a single operator using the same instrument.
• C. Variation between operators or setups.
• D. Overall process variation.

Answer: (C)

Reproducibility captures how much measurements vary when different operators or different measurement setups are used. In a gauge R&R study, the total variation from measurements is split into repeatability (variation when the same operator uses the same instrument) and reproducibility (variation due to different operators or different setups). So the focus is on the differences introduced by who is measuring or by changing the setup, not by a single operator or by the overall process. The other concepts are either the opposite (variation within a single operator is repeatability) or broader than reproducibility (overall process variation).
