which of the following is a characteristic of the analysis that a regression model should use? what is the difference between main effect and interaction? which is a difference between detection of an interaction, main effect, or interaction? does detection require more power why is the power to detect an interaction limiting does the power of the interaction depend on the power of the main effect and interaction. what is power to detect interaction does detection of an interaction require more or less power? can you detect an interaction what is the power of an interaction? why is power needed for detection why is power needed to detect interaction what would be the power to detect an interaction in a linear regression model what is the power needed to detect a interaction is power necessary to detect interaction? what is the difference between a regression and a main effect analysis? why does power need to be used in regression why is there a power difference between main effect and interaction of the spss why is power needed when testing for interaction what are main effects and interactions
