## The Median

## The Median is the middle value, the fiftieth percentile (P

_{50}). 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.
