Average Calculator
Calculator and formula for calculating the average of a data serie
This function calculates the average of a data serie. The average is calculated by dividing the sum of the data by their number. The arithmetic mean of a sample is also called the empirical mean.
To perform the calculation, enter a series of numbers. Then click the 'Calculate' button.
Input format
The data can be entered as a series of numbers, separated by semicolons or spaces. You can enter the data as a list (one value per line). Or from a column from Excel spreadsheet by copy & paste

Formulas for the average
The average of a series of numbers is calculated by dividing the sum of the numbers by their number.
\(\displaystyle \overline{x} =\frac{1}{n}(x_1+x_2+...+x_n) = \frac{1}{n} \sum^n_{i=1} x_i \)
Example
\(\displaystyle \overline{x} =\frac{1}{5} ·(5+3+4+2+6) =4 \)
