Document Summary
Factorial design: any study with more than one iv (usually 2-4 iv) Identify factorial designs: a factorial design (factor = iv) is described with a numbering system that indentify the number of iv and number of levels of each var. (*distinguish the fid b/t iv and level). Using a form of 2 3 (2 by 3) means 2 iv and 3 levels for each iv: the conditions can be also indentified by looking at all possible combinations of dif levels of each iv. Total # of conditions = #s of cells in the matrix = product( ) of the #s in the notation. # of level in each iv: 2 levels for 1st iv and 3 levels for 2nd iv. P247 (graph example: 2 way anova (inferential stats: are these mean dif significant) : There are three conditions need to have a anova test: 1] condition 1 f-test 2] condition 2.
