Document Summary
Lecture 8: more than one independent variable is manipulated, each independent variable is referred to as a factor, factorial designs have as many factors as there are independent variables, ex. The impact of one factor on the dependent variable when controlling for all other factors in the experiment. F(1,182) = 81. 15, p < . 001: marginal means. When means are combined across the levels of another factor, they are said to control for or collapse across the efects of the other factors. Ex. for condiion of race; white (m = 5. 08), black (m = 5. 16: interacion. A patern of means that may occur in a factorial design when the inluence of one independent variable on the dependent variable is diferent at diferent levels of another independent variable. The efect of one factor within a level of another factor. Ex. black within strong, ambiguous and weak qualiicaion condiions.
