Document Summary

Psyc 300b - chapter 9: multi-factorial research designs: multi-factorial research designs: involves 2 or more factors (ivs), each with more than 1 level, & 1 dv in a single balanced design. Analyzed as a single experiment rather than a series of 1-way designs: remains at 0. 05, thus type i error is not in ated. Factor (independent variable): labeled on the outside of the data matrix. Levels (subgroups of that factor): a sub-heading, labeled outside of matrix. Marginal means: the averaged mean score across 1 level of 1 factor: have both row & column marginal means, # of marginal means = adding design label. Determines whether one factor affects the other: row main effect like running a t-test on the means. Determines whether there is an association between factors: interaction: the extent to which the effect of 1 factor varies/changes across levels of a 2nd factor.
