Outliers in an unreplicated two-level factorial design can often distort the normal probability plot of the factor effects.

Consider the 24 factorial design in 2 blocks with ABCD confounded with blocks. Which treatment combination is in the same block as treatment combination a?

The actual levels of the 4 design factors are as follows: A (10, 20), B (5,7), C (50, 100) and D (20, 40).  Suppose that the experimenter selects a model with the terms A, D, and the AD interaction. The predicted response from this model when these factors are at levels A = 16, D = 36 is
