I would like to know how to interpret the result when the interaction term is significant while both of the main effects are not.
For instance, I would like to understand the direct effect of A and moderating effect of B on dependent variable D. The results show that the direct effect of A and B are insignificant. However, the interaction term of A and B is significant.
1. In this case, should I interpret that there are no direct effect of either A or B, yet the B moderates the direct effect of A?
2. Is it okay to plot an interaction chart while there are no direct effects available?
Thank you very much!
