across this range, even when the naive probability for a sample number taking one certain value from infinitely many is zero. In this context, the analog of a weighted average, in which there are infinitely many possibilities for the precise value of the variable in each range, is called the

In general application, such an oversight will lead to the average value artificially moving towards the middle of the numerical range. A solution to this problem is to use the optimization formulation (that is, define the mean as the central point: the point about which one has the lowest

This equality does not hold for other probability distributions, as illustrated for the log-normal distribution here. 386: 1745:, the former being twice the latter. The arithmetic mean (sometimes called the "unweighted average" or "equally weighted average") can be interpreted as a special case of a weighted average in which all weights are equal to the same number ( 1264: 1625:

is the distance from a given number to the mean, one way to interpret this property is by saying that the numbers to the left of the mean are balanced by the numbers to the right. The mean is the only number for which the

The arithmetic mean of a set of observed data is equal to the sum of the numerical values of each observation, divided by the total number of observations. Symbolically, for a data set consisting of the values

A weighted average, or weighted mean, is an average in which some data points count more heavily than others in that they are given more weight in the calculation. For example, the arithmetic mean of

There are applications of this phenomenon in many fields. For example, since the 1980s, the median income in the United States has increased more slowly than the arithmetic average of income.

for which a few people's incomes are substantially higher than most people's, the arithmetic mean may not coincide with one's notion of "middle". In that case, robust statistics, such as the

504: 137:. The term "arithmetic mean" is preferred in some mathematics and statistics contexts because it helps distinguish it from other types of means, such as 1846:
If a numerical property, and any sample of data from it, can take on any value from a continuous range instead of, for example, just integers, then the

If elements in the data 4515: 1083:, then the arithmetic mean of the numbers does this best since it minimizes the sum of squared deviations from the typical value: the sum of 2530: 2209: 421: 4665: 4289: 2930: 1283:
The arithmetic mean of any amount of equal-sized number groups together is the arithmetic mean of the arithmetic means of each group.

The arithmetic mean has several properties that make it interesting, especially as a measure of central tendency. These include:

Thus, these could easily be called 1° and -1°, or 361° and 719°, since each one of them produces a different average. 951: 4312: 4204: 2444: 2388: 100: 2461: 981: 4917: 4490: 4364: 1370:, as is the median. However, when we consider a sample that cannot be arranged to increase arithmetically, such as 1306:
when placed in some order, then the median and arithmetic average are equal. For example, consider the data sample
