Mean

In mathematics, mean has several different definitions depending on the context.

In probability and statistics, mean and expected value are used synonymously to refer to one measure of the central tendency either of a probability distribution or of the random variable characterized by that distribution. In the case of a discrete probability distribution of a random variable X, the mean is equal to the sum over every possible value weighted by the probability of that value; that is, it is computed by taking the product of each possible value x of X and its probability P(x), and then adding all these products together, giving . An analogous formula applies to the case of a continuous probability distribution. Not every probability distribution has a defined mean; see the Cauchy distribution for an example. Moreover, for some distributions the mean is infinite: for example, when the probability of the value is for n = 1, 2, 3, ....

For a data set, the terms arithmetic mean, mathematical expectation, and sometimes average are used synonymously to refer to a central value of a discrete set of numbers: specifically, the sum of the values divided by the number of values. The arithmetic mean of a set of numbers x₁, x₂, ..., x_n is typically denoted by , pronounced "x bar". If the data set were based on a series of observations obtained by sampling from a statistical population, the arithmetic mean is termed the sample mean (denoted ) to distinguish it from the population mean (denoted or ).

Otto

Otto is a masculine German given name. It originates as an Old High German short form (variants Audo, Odo, Udo) of Germanic names beginning in aud-, an element meaning "wealth, prosperity".

The name is recorded from the 7th century (Odo, son of Uro, courtier of Sigebert III). It was the name of three 10th-century German kings, the first of whom was Otto I the Great, the first Holy Roman Emperor, founder of the Ottonian dynasty.

The Gothic form of the prefix was auda- (as in e.g. Audaþius), the Anglo-Saxon form was ead- (as in e.g. Eadmund), the Old Norse form was auð-.

The given name Otis arose from an English surname, which was in turn derived from Ode, a variant form of Odo, Otto.

Due to Otto von Bismarck, the given name Otto was strongly associated with the German Empire in the later 19th century. It was comparatively frequently given in the United States (presumably in German American families) during the 1880s to 1890s, remaining in the top 100 most popular masculine given names in the US throughout 1880–1898, but its popularity decreased significantly after 1900 with increasing anti-German sentiment leading up to World War I; it fell below rank 200 in 1919, below rank 500 in 1947, and below rank 1000 in 1975; it re-entered the top-1000 most popular given names in the US only in the 2010s, ranking 696th as of 2013.

Jimmy Fallon

James Thomas "Jimmy" Fallon (born September 19, 1974) is an American comedian, television host, actor, singer, writer, and producer. He is known for his work in television as a cast member on Saturday Night Live and as the host of late-night talk show The Tonight Show Starring Jimmy Fallon. He was born in Bay Ridge, Brooklyn and raised in Saugerties, New York. He grew up with an interest in comedy and music, moving to Los Angeles at 21 to pursue stand-up opportunities.

He was commissioned to join NBC's Saturday Night Live as a cast member in 1998, fulfilling a lifelong dream. Fallon remained on SNL for six years between 1998 and 2004, co-hosting the program's Weekend Update segment and becoming a celebrity in the process. He left the program for the film industry, starring in films such as Taxi (2004) and Fever Pitch (2005). Following his film career, Fallon returned to television as the host of Late Night with Jimmy Fallon on NBC in 2009, where he became well known for his emphasis on music and games. He transitioned from that program to become the sixth host of the long-running The Tonight Show in 2014.

The Tonight Show

The Tonight Show is an American late-night talk show broadcast from the Rockefeller Center in New York City and airing on NBC since 1954. It is the world's longest-running talk show, and the longest running, regularly scheduled entertainment program in the United States. It is the third-longest-running show on NBC, after only the news-and-talk shows Today and Meet the Press.

Over the course of more than 60 years, The Tonight Show has undergone only minor title changes. It aired under the name Tonight for several of its early years, eventually settling on The Tonight Show after the seating of long-time host Johnny Carson in 1962. In later decades, network programmers, advertisers, and the show's announcers would refer to the show by including the name of the host; for example, it is currently announced as The Tonight Show Starring Jimmy Fallon. In 1957, the show briefly tried a more news-style format. It has otherwise remained a talk show throughout its run.

The Tonight Show began broadcasting in 1954. It has had six official hosts, beginning with Steve Allen (1954–57), followed by Jack Paar (1957–62), Johnny Carson (1962–92), Jay Leno (1992–2009, 2010–14), Conan O'Brien (2009–10), and Jimmy Fallon (2014–present). It has had several recurring guest hosts, a practice especially common during the Paar and Carson eras.
