The median is a measure of central tendency and indicates the middle score of a group,but does not indicate the variability of the scores around the mean.A measure of dispersion is required to demonstrate the distribution of scores.The same median score does not mean the average score,or the mean,is the same.The same median score does not mean that the most frequent,or mode,is the same.The same median does not equate to sameness in other ways.
