About Bartlett's Test
Bartlett's test assesses whether multiple groups have equal variances.
Caution: Very sensitive to departures from normality. If data is not normal, use Levene's test instead.
Null hypothesis: All groups have equal population variances.
Use when: Data is approximately normal and you need to test variance homogeneity.
