RE: atan(r) values of second level results
Hi,
I'd like to follow up on this post after searching on a similar head-scratcher. I see the difference between the two Z/z values above, thanks. However, I'm unsure how r-values of 0.05-0.29 are considered correlated; these values seems low.
In our groups work, we're comparing two conditions. There is a strong effect size and near significant p (p=0.0527) when I compare connectivity values (i.e. fisher transformed Z-values) between conditions but the individual conditions don't seem very correlated with the task (they have mean fisher values of -0.05411 and 0.116).
Other information:
I performed a PPI (regression (bivariate)) analysis with 14 subjects.
