Question: The means of each group of a two-way analysis of variance for two independent variables are plotted as shown in the graph. What does the graph represent about the interaction of the variables?



A ) Disordinal interaction
B ) Ordinal interaction
C ) No interaction

Steps to derive

1 When there is no significant interaction effect among the variables, the lines in the graph will be parallel or approximately parallel.

2 The given two lines are parallel to each other, so they represent 'no interaction'.



Hence the right answer is Option C
