Document Summary

Factors when 2 or more ivs are combined in a single study. Levels a notation system that identifies both the number of factors and values. Can see how an individual factor and a group of factor, when acting together, influence behavior. Main effect the mean differences among the levels of one factor. A statistical test is necessary to determine whether the interaction is significant. Interaction between factors one factor either/not having a direct influence on the effect of a second factor: independent factors have no interaction. Interaction the factors when the effects of one factor depend on the different levels of a second factor. Significant effects indicated by a statistical analysis: main effects may present a distorted view of the actual outcome. Each main effect is an average it may not accurately represent any of the individual effects that were used to compute the average.
