Document Summary
Chapter 10: complex experimental designs: researchers often investigate probs that demand more complicated designs. An independent varaibel can have more than two levels. Interpretation of factorial designs: factorial designs yield 2 distinct kinds of info, main effect: info about the effect of each iv taken by itself, interaction: In a design with 2 ivs, there are 2 main effects (one for each iv) If there"s an interaction bw (cid:884) ivs, the way that one iv affecs the: these are new and valuable sources of info that can"t be obtained in a single-experimental design wher e only one iv is manipulated. Dv depends on the particular level of the other variable. Simple main effect of independent variable a: here we can look at the simple main effect of a, food selection within each level of b, compare the 2 food selections when the companion is either obese or thin.
