Arithmetic Mean Average

An average calculated by adding the value of the points in a data set and dividing the sum by the number of data points. For example, suppose one wishes to calculate the average income of a country with exactly five people in it, and their incomes are $25,000, $26,000, $43,000, $70,000, and $72,000. It is calculated as:

($25,000 + $26,000 + $43,000 + $70,000 + $72,000) / 5 = $47,200.

A limitation to the arithmetic mean average is that it can be overly affected by extremes in either direction. For example, if one of the five persons in the country earns $100 billion per year, the arithmetic mean average income would be in the billions and would not accurately count the other four citizens. For this reason, many analysts use the median in conjunction with the arithmetic mean average. The arithmetic mean average is also called simply the mean.

[H.sub.0]: We suppose that arithmetic mean of perceiving of the importance of personal presentation on social networks from the point of view of job search by male (nowadays and in the future) is equal to arithmetic mean of perceiving of the importance of personal presentation on social networks from the point of view of female and also we assume that the difference between them, if it exists, is caused only by coincident variation of selection results.
As discussed in Section II, using the log-linearized model will generally lead to inaccurate estimates of the difference in the arithmetic mean of wages if the shapes of those wage distributions differ.
Then trimmed winsorized and modifiedmeans were used instead of arithmetic mean in ANOVA and type-I error rates were estimated under these circumstances.
Note that, for all [a.sub.i], [p.sub.j] = 1/n obtains the probabilistic harmonic arithmetic weighted harmonic average (PHAWHA) and [v.sub.i] = 1/n, for all a,, obtains the probabilistic harmonic arithmetic mean (PHAM) operator.
The arithmetic mean provides a value of the variable which represents the centre of gravity of the distribution (in which the distribution of observations is balanced).
