Average In colloquial language, an average is the sum of a list of numbers divided by the number of numbers in the list. In mathematics and statistics, this would be called the arithmetic mean.However, the word average may also refer to the median, mode, or other central or typical value. In statistics, these are all known as measures of central tendency.n mathematics and statistics, this would be called the arithmetic mean.

mean Related Terms. Simple or arithmetic average of a range of values or quantities, computed by dividing the total of all values by the number of values. For example, the mean of 1, 2, 3, 4, and 5 is (15 ÷ 5) = 3. It is the most common and best general purpose measure of the mid-point (around which all other values cluster) of a set of values, but is prone to distortion by the presence of extreme values and may require use of a measure of distortion (such as mean deviation or standard deviation).

Mean, Median, Mode, and Range Just remember the following: mean: regular meaning of average median: middle value mode: most often. (In the above, I've used the term average rather casually. The technical definition of average is the arithmetic mean: adding up the values and then dividing by the number of values.ut there is no middle number, because there are an even number of numbers. In this case, the median is the mean (the usual average) of the middle two values: (2 + 4) ÷ 2 = 6 ÷ 2 = 3. The mode is the number that is repeated most often, but all the numbers in this list appear only once, so there is no mode.

- Mx = M M is the greek letter mu, by the way. Statistically speaking, an average of averages within a sample is said to very closely approximate the population average. However, where the sample size is under 30, there needs to be an adjustment for size.he mean is the average you're used to, where you add up all the numbers and then divide by the number of numbers. The median is the middle value in the list of numbers. To find the median, your numbers have to be listed in numerical order, so you may have to rewrite your list first.

Why Knowing a Mean (or Average) Is Useful in Psychology In statistics, the mean is the mathematical average of a set of numbers. The average is calculated by adding up two or more scores and dividing the total by the number of scores. Consider the following number set: 2, 4, 6, 9, 12. The average is calculated in the following manner: 2 + 4 + 6 + 9 + 12 = 33 / 5 = 6.6.

median One type of average, found by arranging the values in order and then selecting the one in the middle. If the total number of values in the sample is even, then the median is the mean of the two middle numbers. The median is a useful number in cases where the distribution has very large extreme values which would otherwise skew the data. Use median in a sentence.

Difference Between Average and Mean An average can be described in many ways. Aside from expressing it as the mean of the sample, it can also be given as the median or the mode. Median is the central point of the set. In statistics, it is usually the number that occurs in the middle of a set of numbers. A description of the average can be in the median, some of the time, if it is considered as the most suitable way to describe the central tendency of a particular sample.
