The Median

The Median is the middle value, the fiftieth percentile (P50).  If there is an odd number of cases in a distribution, the median is the middle recorded observation.  If the sum of cases is even, the median is the mean of the two central observations.

Median= 8

Note: while the Mean gives equal weight to all members in a population, the Median takes only one case, the middle case, as a representative value for the distribution.

The next measure of central tendency is the Mode.
