what is the difference between interaction and main impact? what is main effect in the interaction if there is an interaction between two independent variables, then there will always be main effect. if the interaction between two independent variables is constant, the main effect of each variable is a _____. how does an interaction with an independent variables work? which type of data would be used to demonstrate the difference between an interaction and a main effect what is the difference between an interaction and a main effect? what type of data does a data interaction have what are the main effects if there are two independent variables main effect of a variable in data can i get an interaction between two independent variables and a main effect without main effects is there an interaction between independent variables what is the difference between the independent and interdependent variables? why do there are main effects which condition is not always the case with a independent variable and a main effect why is there main effect for independent variables is an interaction a main effect or an interaction what is the main effect of a variable interaction can an interaction between two independent variables cause an interaction? why are there two independent variables that have main effects and interaction with each other?
