Uncertainty in interlaboratory comparisons using the weighted mean or arithmetic average as a reference value
Języki publikacji
Abstrakty
Zagadnienie niepewności przy wyborze sposobu wyznaczania wartości odniesienia może być istotne dla laboratoriów pilotujących porównania. Dotyczy to zarówno porównań kluczowych jak i uzupełniających. W ich wyniku otrzymuje się wartość odniesienia. Wartość tę można wyznaczać jako średnią ważoną lub średnią arytmetyczną wszystkich uzyskanych wyników porównania.
The problem of uncertainty in choosing the manner of evaluation of reference value may be significant for pilot laboratory. It concerns key comparisons as well as supplementary comparisons. The result of these comparisons is a reference value. This value may be determined as a weighted or arithmetic mean of all results obtained in measurement comparison.
