Web7 nov. 2016 · In simple terms, variance refers to the data spread or scatter. Statistical tests, such as analysis of variance (ANOVA), assume that although different samples can come from populations with different means, they have the same variance. Equal variances (homoscedasticity) is when the variances are approximately the same across the samples. WebThis is commonly referred to as the assumption of homogeneity of variance-covariances matrices. To the extent that the sample sizes are disparate and the variances and covariances are unequal, MANOVA yields invalid results.
