I conducted an experiment with 2 independent group variables (gender and language - language indicates either native speakers or 2nd language speakers) and ran a 2 way ANOVA. There were no main effects, and no interaction. My hypotheses had been that there would be main effects and interaction. So, I rejected all 3 hypotheses. I discussed what the reason may have been for having no main effects. Do I separately need to discuss the reasons for no interaction?
Also, even through the interaction did not reach significance, there was a 'trend' for males to perform better in a second language, while for females to perform better in their first language. Do I need to comment on that if I already mentioned it in results section?
