Median Definition from Social Science Dictionaries & Glossaries
Glossary of Sociology
The number that falls halfway in a range of numbers--the score below which are half the scores and above which are the other half. The median is a way of calculating 'central tendency' which is sometimes more useful than calculating a mean (particularly when many extreme scores are in the distribution).

Is the measure used to summarize the varying lengths of absences from work among the cases with days away from work. Half the cases involved more days and half involved less days than a specified median.

Electronic Statistics Textbook
A measure of central tendency, the median (the term first used by Galton, 1882) of a sample is the value for which one-half (50%) of the observations (when ranked) will lie above that value and one-half will lie below that value. When the number of values in the sample is even, the median is computed as the average of the two middle values.
See also, Descriptive Statistics.
Common Concepts in Statistics
The value that divides the frequency distribution in half when all data values are listed in order. It is insensitive to small numbers of extreme scores in a distribution. Therefore, it is the preferred measure of central tendency for a skewed distribution (in which the mean would be biased). The median test assesses the statistical significance of the difference between two medians. (Online Median Test.)
Median Definition from Encyclopedia Dictionaries & Glossaries
Wikipedia English - The Free Encyclopedia
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 of {3, 5, 9} is 5). If there is an even number of observations, then there is no single middle value; the median is then usually defined to be the mean of the two middle values (the median of {3, 5, 7, 9} is (5 + 7) / 2 = 6), which corresponds to interpreting the median as the fully trimmed mid-range. The median is of central importance in robust statistics, as it is the most resistant statistic, having a breakdown point of 50%: so long as no more than half the data is contaminated, the median will not give an arbitrarily large result. A median is only defined on ordered one-dimensional data, and is independent of any distance metric. A geometric median, on the other hand, is defined in any number of dimensions.

Median Definition from Society & Culture Dictionaries & Glossaries
Social Work in Canada
a measure of central tendency, which appears in the middle of an ordered sequence of values. eg. the median wage is the point at which half made more and half made less. If you place the series in ascending or descending order, the median is the number that divides the series into two parts each containing the same number of data. When there is an even number of data, determine the two central values and take the arithmetic mean.
Environmental Engineering (English ver.)
(Statistics) In a set of observations, the middle-most value with an equal number of observations lying above and below the median value. Also see Mean and Mode.
