### Median

In a series of numbers, the median is a number which has at least half the values greater than or equal to it and at least half of them less than or equal to it.

### Median

A measure of central tendancy where half the scores are above and half below.

A descriptive statistic used to measure central tendency. The median is the score/value that is exactly in the middle of a distribution (i.e. the value above which and below which 50% of the scores lie)

In statistics and probability theory, the median is the numerical value separating the higher half of a data sample, a population, or a probability distribution, from the lower half. The median of a finite list of numbers can be found by arranging all the observations from lowest value to highest value and picking the middle one (e.g., the median ...

A median is a form of mean in which a set of numbers is arranged in an ascending or descending scale and the middle number (if there are an odd number in the set) or the arithmetic mean of the middle two numbers (if there are an even number) is taken as the median. This can give a more representative average in some circumstances than an arithmetic...

If a distribution of wages, income, turnover, etc, is sequenced, the median is the value which splits this distribution into two equal parts. For a distribution of wages, for example, the median is the wage below which 50% of salaries are situated. Equivalently, it is the wage above which 50% of salaries are situated.
