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.It is sometimes stated that the 'mean' means average. This is incorrect if "mean" is taken in the specific sense of "arithmetic mean" as there are different types of averages: the mean, median, and mode. For instance, average house prices almost always use the median value for the average.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); see the Cauchy distribution for an example.
