Document Summary
To examine non-linear effects of iv, the iv must have three or more levels. To examine whether a variable acts as a moderator simply incorporated into the factorial design as an additional. Produces an interaction then it is a moderator. Experimental design that incorporates at least one subject variable along with at least one manipulated situational variable. Every level of each iv is combined with every level of all the other iv. Factorial design in which each subject engages in only one condition. Factorial design in which each subject engages in every condition. Factorial design that includes at least one between- subjects variable and at least one within-subject variable. Described numerically as, for example, a 2 x 4 x 3 design. Three numbers indicate that there are 3 ivs. "2" tells that first iv has two levels. "4" tells that second iv has 4 levels. "3" tells that third iv has 3 levels.
