I need to perform a wilcoxons signed-rank test in python and I've chosen "scipy" library to do it. However I have some problems when interpreting the results, as I don't know how to asses the directionallity of the difference when they are statistically significant.
According to the description of the Wilcoxon function, the output is the following:
T : float. The sum of the ranks of the differences above or below zero, whichever is smaller.
p-value : float. The two-sided p-value for the test.
So, my question is: when the p-value is significant, how can I know if its due to the fact that A > B or A < B? Is T giving me this information? Would it be as easy as comparing the medians of both groups?
Thanks a lot in advance!
