To calculate the magnitude of effect estimates for a factorial design, the methods are
A) radically different from the methods used with a one-way design.
B) simple extensions of the methods used with a one-way design.
C) not possible to calculate.
D) only useful for estimating magnitude of effects for interactions, not main efforts.

Question

Quizplus · Accepted Answer

The methods used to calculate the magnitude of effect estimates for a factorial design are simple extensions of the methods used with a one-way design. This involves calculating the mean differences between the levels of each factor separately, as well as calculating the main effects and interactions. Therefore, option B is correct.
