Using the Median For 4 marks, answers for each condition are correct (Group A = 5.5, • Group B = 12.5) and for each condition scores are arranged in ascending order with middle values indicated. For 3 marks, there is one correct median and two sets of scores correctly • arranged as calculations, or vice versa. For 2 marks, there are two correct medians and no calculations, or one • correct median and one set of scores correctly arranged as calculations. For 1 mark, there is one correct median or one set of scores correctly • arranged as calculations.
