Null hypothesis: The mean frequency of childhood abuse experience is equal to antisocial father in childhood.

H0: Xc=Xa

This is my research hypothesis that I choose above but I need help in what my teacher is asking me.

My standard deviation is 4.9 or 5

1.How big a difference between the means of the two groups on the variable would you consider meaningful, and why?

1. How big a difference between the means of the two groups would you consider NOT meaningful, and why?
2. What would it mean if the meaningful difference was 'statistically significant', p < .05?
3. What would it mean if the meaningful difference was NOT 'statistically significant', p > .05?
4. What would it mean if the meaningless difference was 'statistically significant', p < .05?
5. What would it mean if the meaningless difference was NOT 'statistically significant', p > .05?
