Mean - Truncated mean

In statistics, mean has two related meanings: the average in ordinary English, which is more correctly called the arithmetic mean, to distinguish it from geometric mean or harmonic mean. The average is also called sample mean. the expected value of a random variable, which is also called the population mean. As well as statistics, means are often used in geometry and analysis; a wide range of means have been developed for these purposes, which are not much used in statistics. See the Other m ...

The arithmetic mean is the "standard" average, often simply called the "mean". The mean may often be confused with the median or mode. The mean is the arithmetic average of a set of values, or distribution; however, for skewed distributions, the mean is not the same as the middle value (median), or most likely (mode). For example, mean income is skewed upwards by a small number of people with very large incomes, so that the majority have an income lower than the mean. By contrast, the median income is the l ...

The interquartile mean is a specific example of a truncated mean. It is simply the arithmetic mean after removing the lowest and the highest quarter of values. assuming the values have been ordered. ...

In calculus, and especially multivariable calculus, the mean of a function is loosely defined as the average value of the function over its domain. In one variable, the mean of a function f(x) over the interval (a,b) is defined by (See also mean value theorem.) In several variables, the mean over a relatively compact domain U in a Euclidean space is defined by This generalizes the arithmetic mean. On the other hand, it is also possible to generalize the geometric mean to functions by defining the geometric ...

The generalized mean, also known as the power mean or Hölder mean, is an abstraction of the Arithmetic, Geometric and Harmonic Means. By choosing the appropriate value for the parameter m we can get the arithmetic mean (m = 1), the geometric mean (m -> 0) or the harmonic mean (m = -1) This could be generalised further as and again a suitable choice of an invertible f(x) will give the arithmetic mean with f(x)=x, the geometric mean with f(x)=log(x), and the h ...

The geometric mean is an average that is useful for sets of numbers that are interpreted according to their product and not their sum (as is the case with the arithmetic mean). For example rates of growth. Mean - An example. An experiment yields the following data: 34,27,45,55,22,34 To get the geometric mean How many items? There are 6. Therefore n=6 What is the product of all items? It is 1699493400. To get the geometric mean take the nth (the 6th) root of that pro ...

The harmonic mean is an average which is useful for sets of numbers which are defined in relation to some unit, for example speed (distance per unit of time). Mean - An example.

The weighted mean is used, if one wants to combine average values from samples of the same population with different sample sizes: The weights wi represent the bounds of the partial sample. In other applications they represent a measure for the reliability of the influence upon the mean by respective values. ...
