Hello all,

I have two series,one before an event and the other after the event, that I want to see if they are statistically significant different.I transformed them so they will both be Gaussian. I used a student's t-test and I found that they are different for p<0.001. How can I tell if they are positively or negatively correlated?I compared their mean value and I said that since the second one has a larger value then the correlation is positive.Is this correct or shall I use a test such as spearmann's correlation coeeficient?

thank you,

naimead
