Let us assume that an effect of a treatment is to be assessed and the pre- and -post treatment data were
collected for every subject and ready to be analyzed. Select the true statement:
(i) One should nd the differences for each subject, and test the hypothesis about the difference being 0 against
one of the three possible alternatives.
(ii) One should study the difference of the medians in both populations against suitable alternative hypothesis
using separate independent samples (pre and post treatment).
(iii) Both (i) and (ii) above are equally good.
(iv) Both could be used but one approach is more efficient than the other (state which one if you select this answer).
(v) none of the above is true.
