Indexes that do this are known as arithmetic averages.

The simple arithmetic average of the estimates, still used by many log analysts, introduces even larger errors.

Many notable mean operators such as the max, arithmetic average, median and min, are members of this class.

The arithmetic averages are different, but are they statistically different from each other?

For example, since the 1980s in the United States median income has increased more slowly than the arithmetic average of income.

Arithmetic averages have a drawback, too: their returns will always be higher than what an investor would earn by buying and holding the average stock.

A third "symmetrized" Theil index is the arithmetic average of the two previous indices.

The mean is the arithmetic average; the standard deviation is a measure of variation from that average.

Conventionally, this means an arithmetic average.

If elements in the sample data increase arithmetically, when placed in some order, then the median and arithmetic average are equal.

In financial trading, typical price (sometimes called the pivot point) refers to the arithmetic average of the high, low, and closing prices for a given period.

This difference is caused by the way arithmetic averages deal with underperforming and overperforming stocks in order to preserve stocks' equal weight.

The value denotes a conveniently chosen midpoint between and (such as the geometric average or the arithmetic average ).

The mean chain length of an entire web is the arithmetic average of the lengths of all chains in a food web.

The squared sample distance covariance is simply the arithmetic average of the products A'B:

The outliers would greatly change the estimate of location if the arithmetic average were to be used as a summary statistic of location.

For example, R is the arithmetic average of the absolute values and R is the range of the collected roughness data points.

But averaging the logarithm of stocks' percentage gains causes an excessive correction of the upward bias of arithmetic averages.

This applies for any weighting system (market weights, price weights, equal weights), as long as the index is an arithmetic average or total.

Early on, the initial divisor was composed of the original number of component companies; which made the DJIA at first, a simple arithmetic average.

The index is the arithmetic average of the change of prices between a time and a base time 0, which is the end of the preceding quarter.

He said the 29 percent increase was "an arithmetic average" of increases for various grades of gasoline and diesel, and declined to give specific increases by refined product.

Instead of averaging stocks' percentage changes, it would base the indexes on an average of those changes' logarithms, which results in lower returns than those of arithmetic averages.

Mr. Mercurio attributes the increase in the median price of co-ops to a "surge in sales of high-end apartments, some costing up to $300,000, which brought up the arithmetic average."

But in elementary statistics, students are immediately taught that an arithmetic average can be highly misleading when a distribution is skewed; a median (the middle value) is more enlightening in such a case.
