What Is The Homogeneity Of Variance Assumption. Both tests require the homogeneity assumption. Could someone tell me if this is correct.
Mar 27 2021 a Is a test of the homogeneity of variance assumption underlying ANOVA b Should be ignored at all times c Is a test of the homogeneity of variancecovariance matrices d Is applicable only for split-plot designs. That is in an ANOVA we assume that treatment variances are equal. A large mean difference and small sample variances.
Who cares Both t-test and ANOVA are sensitive to a violation of the assumption of homogeneity of variance.
In short homogeneity of variance-covariance matrices concerns the variance. Mar 27 2021 a Is a test of the homogeneity of variance assumption underlying ANOVA b Should be ignored at all times c Is a test of the homogeneity of variancecovariance matrices d Is applicable only for split-plot designs. The homogeneity of variance assumption states that the two population variances are equal. Also I describe three different types of Levenes tests two of which are.
