“What is the mean calculation” question is one of the most
difficult to understand concepts, although it is very easy to answer
mathematically. We use **mean calculator **everywhere.
For example, if you want to calculate your school grade or in the economy, in
production, in statistics, etc. you have
to use **mean calculator** for correct
results. The mean is a measure of central tendency. The mean is affected by
very large and very small values in the data set. It is a good way to estimate
and predict the average state of arithmetic in groups of data without such
values. In general, the mean is a number obtained by summing up all practical
or theoretical data arrays and dividing them by the number of aggregate data.
So how work **mean calculator **?

The mean is obtained by dividing the sum of all terms in a
data set by the number of terms.

We can formulate as “Mean = sum of all data / number of data ".

For example : What is the mean of the 5,5,5,5,5,5,5 number
array?

It’s so easy to calculate. First collect all the numbers. It
is 35. Then divide it how many numbers you have. Result is 35 /7 = 5. In
addition, if all numbers are the same, mean will also the same with numbers.
Because there isn’t any differences between numbers.

It is the average of the centralized location measure which uses most in both the descriptive statistics field and the inferential statistics field in statistical science field.
