Abstract

U ovome diplomskome radu provedena je statistička analiza rezultata međulaboratorijskih
usporedbi. Opisana je mjeriteljska infrastruktura, od svijetske pa sve do nacionalne razine u
Hrvatskoj s posebnim naglaskom na provođenje međulaboratorijskih usporedbi. Zatim je
objašnjen postupak statističke obrade rezultata mjerenja primjenom zadane referentne
vrijednosti, referentne vrijednosti određene težinskom srednjom vrijednosti te referentne
vrijednosti određene aritmetičkom srednjom vrijednosti. Za tri različite EURAMET
međulaboratorijske usporedbe izvršena je statistička analiza rezultata mjerenja primjenom
različitih statističkih pristupa. Rezultati rada prikazani su tablično i grafički. Na kraju rada
donesen je zaključak s prednostima i nedostacima primjenjenih statističkih metoda na stvarnim
primjerima.

Abstract (english)

The statistical analysis of the results of interlaboratory comparisons was conducted in this
master’s thesis. The metrological infrastructure, from the global to national level in Croatia,
was described with a specific focus on the implementation of interlaboratory comparisons.
Next, the procedure for statistical processing of measurement results was explained, using the
given reference value, the reference value determined by weighted mean, and the reference
value determined by arithmetic mean. For three different EURAMET interlaboratory
comparisons, a statistical analysis of the measurement results was performed using various
statistical approaches. The results of the study were presented in tables and graphs. In
conclusion, the advantages and disadvantages of the applied statistical methods were discussed
based on real examples.
