Document Summary
Number of ivs = how many #s there are __ x __ x __ = 3 ivs. Multiple variables: cell phones and age on driving. The overall effect of 1 iv on the dv. 1 main effect per iv in study. Driving condition - take the average of the slopes and create a new line. Look at the average within each variable. Depends on how much sunlight there is. Depends on how much clothing you"re wearing. Interaction ~ a moderator of 1 iv on the other. Young adults did better w/ the detached reappraisal. Old adults did better w/ the positive reappraisal. Use table for main effects (marginal means) Factorial designs tell us more about complex relationships. Interactions are seen as more important than main effects. We don"t live in a main effect world . We can"t appropriately interpret a main effect w/o understanding how it changes across levels of another variable.
