The '''median''' is that value that separates the highest half of the sample from the lowest half. When we use the ''median'' to describe what the observations have in common, there are several choices for a measure of variability, the '''range''', the '''interquartile range''', and the '''absolute deviation'''. You can find out more about these from a good introductory statistics textbook. The '''mode''' is the value that has the largest number of observations. The '''mode''' is not necessarily unique, unlike the '''mean''' and the '''median'''. ---- [http://netdial.caribe.net/~rabeldin/Home.html RABeldin ]
