Fri, 24 Oct 2014 00:52:07 GMTWith the above info, what's the correct way to determine whether the proportions differ significantly? I thought I had a lovely formula that used upper and lower confidence limits and N to calculate the SD and then just pop into an online calculator, but I have no such formula, and am not sure whether that is the correct approach anyway. Any help would be appreciated - thanks.

I split my sample in 2 groups, participants with condition +M and participants without the condition -M. I calculated correlations and beta coeff( regression by group) so what is the better way to see if these 2 groups differ significantly? the Fischer test for correlations or interaction terms in the regression? Please let me know if I need to provide more details?

Thanks in advance for your help.

PS I am new to this site, how can I give back seeing as I am no expert on stats?
