True or False:

A. You can perform a two-way ANOVA only when the sample sizes are the same in all cells.

B. When interaction is present in a two-way ANOVA, the main effects are always uninformative.

C. ANOVA assumes that the populations are Normal with possibly different means and the same standard deviation and that independent simple random samples are drawn from each population.

D. ANOVA separates the total variation into parts of the model and error. The model variation is separated into parts for each of the main effects and the interaction.

E. There are three null hypotheses in a two-way ANOVA with an F test for each

A) True You can only perform a two way ANOVA only when the sampe sizes are the same in all cell.
B) False The main effects are not always uniformative when interaction is present in a two way ANOVA.
C) True ANOVA assumes that the populations are Normal with possibly different means and the same standard deviation and that independent simple random samples are drawn from each population.

D) True ANOVA separates the total variation into parts of the model and error. The model variation is separated into parts for each of the main effects and the interaction.

E) True There are three null hypotheses in a two-way ANOVA with an F test for each.

Q1. Why would you perform a one-way ANOVA over a t-test?
