 InvestHub.com's Finance Dictionary and Glossary of Investment Terms Median Definition 1.
The midpoint in a range of numbers or observations that are arranged by value. If the number of observations is an even number then the median is found by taking the mean of the two numbers in the middle of the distribution. 50% of the numbers will be above the median and 50% will be below.  Definition 2.
One type of average, found by arranging the values in order and then selecting the one in the middle. If the total number of values in the sample is even, then the median is the mean of the two middle numbers. The median is a useful number in cases where the distribution has very large extreme values which would otherwise skew the data.
