Example:
Independent variable 1: morning and night patterns
Independent variable 2: number of cups of coffee consumed (more, less)
Dependent variable: exam score
The main effect of factor A
———-less——-more
morning patterns—-90——90
night patterns—-60——60
-
The main effect of factor B
———-less——-more
morning patterns—-60——90
night patterns—-60——90
-
The main effects of factor A and factor B
———-less——-more
morning patterns—-60——90
night patterns—-30——60
-
The interaction between factors
———-less——-more
morning patterns—-90——60
night patterns—-60——90
-
Interaction and the main effect of a factor
———-less——-more
morning patterns—-90——60
night patterns—-30——60
-
Sort in order or out of order
Sequential interaction
The direction of the effects of the two independent variables is consistent, but the magnitude of the difference is different
