Dear David, Both variables are positive (right) skewed) and the variables come from the same patients. We want to see the difference between the two variables (that people stay longer in hospital as actually needed). The difference of each person is not so important now....we want to see a whole effect. The results should be presented in mean and SD...(was not my decision...I just have to do the graphs) Thank you.
