Repeating measurements under the same conditions shows how much the results can vary due to random, uncontrollable factors. That spread—the variability—lets you estimate the measurement’s precision and its uncertainty. In verification, you’re not just getting a single value; you’re characterizing how reliable that value is by looking at the distribution of many measurements. The more tightly the results cluster, the higher the precision; a wider spread indicates more variability and less precision. Repeated measurements also help spot outliers and check stability over time.

This isn’t about reducing data collection time—repetition takes more time. It isn’t a guarantee that bias is zero—bias is a systematic offset that requires comparing to a known reference to assess. And although more data can complicate analysis, the payoff is a clear, quantitative picture of precision and variability that verification needs.
