Answer #1

One-way ANOVA:

Advantage: It introduces a single independent variable only.

Disadvantage: Relatively inefficient creating larger estimates of the within-group variance.

ANOVA with Blocking:

Advantage: Randomized blocks design in reducing experimental error since the subject is his/her own control in repeated measures design.

Disadvantage: Information can't be obtained about interactions.

Factorial ANOVA:

Advantage: It allows us to test several hypotheses simultaneously.

Disadvantage: Difficult to experiment with more than two factors or many levels if there is an error in one of the levels within, it can jeopardize a great amount of work.
