For simplicity, let's say I'm trying to show that females (a2) enjoy rock music (b1) more than classical music (b2), but males (a1) enjoy them the same. I run a 2 x 2 between-subjects design study and find that the interaction effect is not significant. However, planned contrasts reveal that females actually do enjoy rock music more than classical music, whereas males enjoy them the same. In this case, is it possible for me to claim that females enjoy rock more than classical music, while males like them the same, even when the interaction effect is non-significant? | |

What is an a priori prediction?
