In statistics and probability theory, median is described as the numerical value separating the higher half of a 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. 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.
A median is only defined on one-dimensional data, and is independent of any distance metric. A geometric median, on the other hand, is defined in any number of dimensions.
In a sample of data, or a finite population, there may be no member of the sample whose value is identical to the median (in the case of an even sample size), and, if there is such a member, there may be more than one so that the median may not uniquely identify a sample member. Nonetheless, the value of the median is uniquely determined with the usual definition. A related concept, in which the outcome is forced to correspond to a member of the sample, is the medoid.
Patrick Douthit (born January 15, 1975 in Winston-Salem, North Carolina), better known as 9th Wonder is a hip hop record producer, record executive, DJ, lecturer, and lyricist from Durham, North Carolina, U.S. He began his career as the main producer for the group Little Brother, and has also worked with Mary J. Blige, Jean Grae, Wale, Jay-Z, Murs, Drake, Buckshot, Chris Brown, Destiny's Child, J. Cole, Kendrick Lamar, Erykah Badu, Ludacris, Mac Miller, and David Banner. As of 2010, 9th Wonder raps under the name of 9thmatic.
9th Wonder has a smooth and soulful production style that relies on samples from artists such as Al Green and Curtis Mayfield. He attributes the bass lines that he uses in production to DJ Premier, Pete Rock and J Dilla, while he claims to have learned "Aahs" from RZA.[clarification needed]
9th Wonder's first significant career breakthrough came in 2003 when, as an up-and-coming producer, he released an unofficial remix album of Nas' 2002 album God's Son entitled God's Stepson. Released through internet outlets, the album garnered significant attention and acclaim. The producer has said that he was not thinking in terms of using it to generate a buzz or promote his skills and that at that point: "I never thought any of this of me as a producer was going to happen." The album has since been credited as starting the now regular trend for unofficial 'home-made' remixes of whole albums.
