Answer to Question 1

The two-way analysis of variance and the randomized block design are similar since they both consider two factors in the model. However, in the randomized block design, the blocking variable is only used for the purpose of exerting improved control over the examination of the single factor of interest. In two-way analysis of variance, we are interested in the effects of two factors and their interaction on the dependent variable.

Answer to Question 2

In the two-way analysis of variance we are interested in the effect of two factors and their interaction on the dependent variable. Therefore, we test for each factor effect and for interaction. In the one-way analysis of variance and the randomized block designs, we are interested in only one factor effect.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
