Tukey test is primarily used for comparing the means of different groups to find out if they significantly differ from each other, not for evaluating the assumption of similar variability (homoscedasticity) across a dataset. Levene's test, Mauchly's test (specifically for sphericity in repeated measures ANOVA), and scatterplots of residuals are methods used to assess the assumption of homogeneity of variances or other assumptions related to variability in the data.
