Precision refers to random fluctuations in measurements, while accuracy (bias) reflects systematic errors. To quantify precision statistically, you collect multiple samples, verify a Gaussian distribution, compute the sample mean and standard deviation, then derive a confidence interval (CI) at a chosen confidence level (CL). The CI gives a range where the population mean is expected to reside with a specified probability. Wider CIs indicate fewer samples or higher variance, and increasing sample count narrows the interval, giving engineers a practical handle on measurement time versus precision trade-offs. ## Full article daily.dev links to this article rather than hosting it.
