Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In mathematics, the Riesz mean is a certain mean of the terms in a series. They were introduced by Marcel Riesz in 1911 as an improvement over the Cesàro mean. The Riesz mean should not be confused with the Bochner Riesz mean or the Strong Riesz mean. In statistics, mean has two related meanings: the arithmetic mean (and is distinguished from the geometric mean or harmonic mean). the expected value of a random variable, which is also called the population mean. There are other statistical measures that use samples that some people confuse with averages - including ''median'' and ''mode.'' Other simple statistical analyses use measures of spread, such as range, interquartile range, or standard deviation. For a real-valued random variable X, the mean is the expectation of X. Note that not every probability distribution has a defined mean (or variance); seethe Cauchy distribution for an example.
