Example 1: In the BBC program The Doha Debates 100 people were surveyed regarding their opinion about capital punishment. 30 were in favor and 70 against.
Purpose: Test for Homogeneity of Variances. Levene's test (Levene 1960) is used to test if k samples have equal variances. Equal variances across samples is called homogeneity of variance.Some statistical tests, for example the analysis of variance, assume that variances are equal across groups or samples.The Levene test can be used to verify that assumption.Levene's test is an alternative to the Bartlett test.ome statistical tests, for example the analysis of variance, assume that variances are equal across groups or samples.
