It is the number obtained by setting the value of the
elements in a number array. To explain in more detail; the numbers on a data in the form x1, x2, x3,
..., xn. Literally, the number obtained by dividing the sum of two or more
numbers by the number of the aggregated numbers. We explained theoretically but
it it also important to learn it practically.
**Avarage calculator** is the most used
central tendency measure in average statistical science.

The average** **symbol
is x̄. In this case, the arithmetic average formula is ;

Average = sum of all data / number of data

With this formula you can calculate averages but there is
easiest way : **avarage calculator. **Enter
the datas and it will calculate !

**Average Disadvantages**

The **average
calculator** is very popular but has
some important disadvantages.

1. It is a central position measure sensitive to extreme
values (ie weak). If the average for the data row is only an extreme value,
either too small or too large, then the average will show that overvalue
approximation.

2.The average can not be used for numerical data of any measurement scale. The average for nominally scaled numeric data is meaningless. The use of arithmetic averaging for sequential scalar numerical data is open to major disputes.

**History Of Average**

Ancient people needed to use numbers and numbers. This period
also knew how to save and store people's needs. They scratched the walls of the
cave where they lived and made a notch on a tree branch to indicate the numbers
of the hunted animals or sheep in the hill. For the first time, ancient people
were writing numbers on the clay tablets for numbers, digging scratches, or
starting to make notches in the cut tree. These signs used by ancient people
are the first written expressions of numbers and numbers.

Besides these; primitive people used different voices and
words to express numbers. Today there are standardized symbols and words that
indicate numbers. Today; numbers, with symbols such as 1, 2, 3, ... and both;
one, two, three, ... words are expressed.
