Question

An experimental method of teaching reading is to be compared to a "traditional method. The main difference between the methods is that the experimental method includes techniques intended to help the very poorest subjects. A test is to be given at the end of six weeks. If the experimental method achieves its goal, which of these differences would probably reflect this fact most clearly? 0 difference between group medians e difference between group means O difference between Ppo for the two groups O difference between Qs for the two groups

Explanation / Answer

here for above difference between group medians and difference between group means both represent that experimental method is effective

however difference between group medians probably reflect this fact most clearly as we do not the distribution of score.

(if more than one option selection allowed ;choose both median and mean option)
