  • kogudispersiooni komponent, mis seostub eri laborite aritmeetiliste keskmiste erinevusega
  • component of the total variance attributable to the difference between the mean values of different laboratories
laboritevaheline dispersioon
Usage examples
  • Kui on võrreldud enam kui ühest laborist saadud tulemusi, siis on tulemuste kogudispersioon tavaliselt laiem kui sama arvu katseid läbi viinud ühe labori tulemuste dispersioon ja erinevatest laboritest saadud keskmiste väärtuste mõningane hajumine ja see põhjustab laboritevahelise dispersiooni suurenemise, mis on kogudispersiooni komponendiks erinevatest laboritest saadud keskmiste erinevuse tõttu.
Good to know
  • Termin “laboritevaheline” on sageli lühendatud “labori”, kui seda on kasutatud tulemuste kogumi dispersiooni esinduslike väärtuste esitamisel, näiteks nagu “laboridispersioon”.
between-laboratory variance
Usage examples
  • When results obtained by more than one laboratory are compared, the scatter is usually wider than when the same number of tests is carried out by a single laboratory, and there is some variation between means obtained by different laboratories, and these give rise to the between laboratory variance which is that component of the overall variance due to the difference in the means obtained by different laboratories.
Good to know
  • The term “between laboratory” is often shortened to “laboratory” when used to qualify representative parameters of the dispersion of the population of results, for example as “laboratory variance”.
