Hi,

this post and the reply have been of great help! 

I do have a question concerning the F-value for the threshold in this situation. How do you calculate which F-value is significant at p < .01 when testing in 1 group the effects of age, behaviour, and their interaction?

The T-value I am using is 2.622 based on a significance level of < .01 and a DF of 110 (111 subjects). Is that correct? 

Many thanks,
Selma
