1. Factorial Design - Has at least two factors (IVs), each with at least two levels - Two IVs can be examined simultaneously 1. Advantages of Factorial Design - More economical in terms of participants - Allows us to examine the interaction of independent variables (assess generalisability) 1. Interactions in Factorial Designs - One IV interacts with another when the effects of one are different depending on the level of the other - And when it changes (moderates or qualifies) the impact of a ...
