Abstrakt<\/h5>\n

Pri pou\u017eit\u00ed anal\u00fdzy rozptylu sa v praxi jav\u00ed ako najproblematickej\u0161\u00ed predpoklad homoskedasticity (rovnosti rozptylov v porovn\u00e1van\u00fdch s\u00faboroch). V takom pr\u00edpade (ak s\u00fa splnen\u00e9 ostatn\u00e9 predpoklady) je mo\u017enos\u0165 vyu\u017ei\u0165 Welchovu anal\u00fdzu rozptylu, pri ktorej sa vo v\u00fdpo\u010dte testovacej \u0161tatistiky rozsahy jednotliv\u00fdch v\u00fdberov nahradia v\u00e1hami, v ktor\u00fdch s\u00fa zahrnut\u00e9 aj v\u00fdberov\u00e9 rozptyly. V pr\u00edspevku sa porovn\u00e1vaj\u00fa v\u00fdhody a nev\u00fdhody klasickej a Welchovej anal\u00fdzy rozptylu prostredn\u00edctvom ve\u013ekost\u00ed ch\u00fdb 1. a 2. druhu pri r\u00f4znych vstupn\u00fdch hodnot\u00e1ch parametrov s\u00faborov. V\u00fdsledkom s\u00fa odpor\u00fa\u010dania pre vo\u013ebu vhodnej met\u00f3dy pre r\u00f4zne kombin\u00e1cie ve\u013ekost\u00ed porovn\u00e1van\u00fdch s\u00faborov a ich variabil\u00edt.<\/p>\n
