Participation reward: 2 Wealth. Reward for a basically correct answer: 9 wealth. (Multiple-choice question) Question: The difference between measurement repeatability and measurement reproducibility lies in ( ). A. Although both refer to the consistency among measurement results of the same quantity being measured, their underlying assumptions are different. B. Repeatability refers to the consistency among multiple consecutive measurement results when the measurement conditions remain unchanged. C. Reproducibility refers to the consistency among measurement results when the measurement conditions change. D. The consistency in repeatability measurements is quantitative, whereas that in reproducibility measurements is qualitative. E. The consistency in repeatability measurements is qualitative, whereas that in reproducibility measurements is quantitative. Answer: ABC. Explanation: The consistency in both repeatability and reproducibility measurements is quantitative.
