Levene's Test
Levene's test of equality of variances is used to assess homogeneity of variance
Levene's Test of Equality of Variances is used in SPSS to assess meeting the statistical assumption of homogeneity of variance in between-subjects designs. Levene's Test of Equality of Variances is a simple statistical test to interpret. If the p-value associated with Levene's test is LESS THAN .05, then the assumption has been violated and you have to make a choice to 1) delete cases in a listwise fashion, 2) conduct a logarithmic transformation on the continuous variable, or 3) utilize non-parametric statistics which are robust to a violation of homogeneity of variance. If the p-value for Levene's Test is MORE THAN .05, the assumption of homogeneity of variance has been met and the parametric statistical test can be interpreted.
This assumption is important when using independent samples t-tests and one-way ANOVA. Click on the buttons below to see how Levene's Test is conducted and interpreted in SPSS.
