For each face-to-face reading, the key comparison reference value, xR, is calculated as the weighted mean of all participants' results. Its standard uncertainty, uR, is calculated as the standard deviation of the weighted mean.
|
| For each face-to-face reading, the degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms, both expressed in milliseconds: Di = (xi - xR) and its expanded uncertainty Ui = 2(ui2 - uR2)1/2. |
| The degrees of equivalence between pair of laboratories have not been computed for this key comparison. |
