Variable brand then fill in: Usage levenetest (y,.) ## s3 method for class 'formula' levenetest (formula, data,.) ## s3 method for class 'lm'.

Of These Tests, The Most Common Assessment For Homogeneity Of Variance Is Levene's Test.

At least one sample has different variance. A p value less than.05 indicates a violation of the assumption. How do you interpret levene’s test?
