Document Summary
2-way interaction: the effect of 1 factor on the dv varies depending on the level of the other factor, the simple main effects of 1 factor are different at the various levels of the other. Simple main effect: the effect of a factor (e. g. audience) at a specific level of another factor (e. g. males) To understand an interaction, need to conduct simple main effect analyses: Do the math: what we do in spss depends on which set of simple main effects we want. The error term for sme depends upon the situation. Examining a between-subject independent variable at a specific level of a. Males and females between each audience condition. Interested in the effect of gender at different levels of audience: 4 f ratios. Increased mean squared effect (means being very different) and error (background noise) Must determine both (ratio) how far each group ratio is pushed above background noise: ex.
