So I have 3 questions
1. Is there a main effect of sex? The p-value is___
2. is there a main effect of practice? ^
3. is there an interaction between sex and practice? ^
We are examining the effects of participant sex and practice on SPSS performance. So its male/female then they are tested 3 times on their ability to perform an ANOVA on SPSS. I don't understand what the difference is between a Main Effect and an interaction?
I also need to find the p-value for all 3. I understand the first one, but how do I find if there is an interaction and where is the p-value of it on SPSS??
thanks
