Answer: b. False
All analysis of variance procedures assume that the compared populations have equal variances.
In all analysis of variance procedures, tests like F-test, Bartlett’s test, Levene’s test and Brown-Forsythe test are used to verify or test the assumption if k samples are from populations with equal variances.
When two or more populations have equal variances, we say that homoscedasticity or homogeneity of variances exist.
The F-test and Bartlett’s test yield best results only if the population is normally distributed. However, Levene’s test and Brown-Forsythe are known to yield good results for data that is not normally distributed.
