Uchambuzi wa Tofauti wa Welch

Welch ANOVA ni jaribio la nadharia tete la kiparameta linalolinganisha wastani wa makundi huru matatu au zaidi wakati tofauti zao (variances) si sawa. Lililoanzishwa na B. L. Welch mnamo 1951, linachukua nafasi ya ANOVA ya njia moja ya kawaida wakati wowote dhana ya usawa wa tofauti (homogeneity-of-variance) inaposhindwa, huku bado likihitaji data ya kawaida (normal) takribani.
