True or False

It is desirable, but not necessary, that sample sizes be equal in a one-factor ANOVA

Tukey\'s test pools all the sample variances

Tukey\'s test with seven groups would entail 21 comparisons of means.

One-factor ANOVA with two groups is equivalent to a two-tailed t-test.

Solution

It is desirable, but not necessary, that sample sizes be equal in a one-factor ANOVA ---> false

Tukey\'s test pools all the sample variances ---> true

Tukey\'s test with seven groups would entail 21 comparisons of means. --> false
