Estimate gauge repeatability and reproducibility

Reference no: EM131136025

In a study to isolate both gauge repeatability and gauge reproducibility, two operators use the same gauge to measure 10 parts three times each. The data are shown in Table 8E.8.

(a) Estimate gauge repeatability and reproducibility.

(b) Estimate the standard deviation of measurement error.
