In a two-factor design, factor A is nested within factor B for which one of the following?
a. at each level of A, each level of B appears
b. at each level of A, unique levels of B appear
c. at each level of B, unique levels of A appear
d. cannot be determined
Homework Answers
Correct option is c:
c. at each level of B, unique levels of A appear
(since A can occur only within B and there should be no interaction)

In a two-factor design, factor A is nested within factor B for
which one of the...

Consider a factorial design model with 2 levels of Factor A, 3 levels of Factor B, and 2 observations at each combination of factor levels. Write this model in matrix notation as Y = X8+ €. Compute the matrices X'X and X'Y and use them to derive the least-squares estimators of all appropriate parameters from the normal equations XXB = X'Y Note: Do not write the matrices for a general factorial design model. Consider the particular factorial design described here.
