Mean Calculator


Mean formula

Enter all numbers separated by a comma to find the mean:


This Mean Calculator calculates the mean of the numbers entered into the form field.

The mean of a set of numbers is the arithmetic average of the numbers. It is all the numbers added together divided by the number of terms entered in. This will yield the mean, or average, of the numbers, as shown in the formula displayed above.

To use this calculator, a user just enters in the set of numbers which he wants to compute the mean for, each number separated by a comma. A comma must be used to separate the values, or else the calculator will not work. Any other delimiter, including a space between numbers, will cause the calculator not to work. Only commas to separate values are recognized. After the set of numbers are entered in, the user clicks the 'Calculate' button, and the resultant mean value will be calculated and displayed.

The units which the mean calculator solves for is the same as the units which are entered into the input field. For example, if the values entered into the input field are in unit inches, the resultant mean value will be in unit inches. The unit does not change from input to resultant value.

Calculating the mean value can be significant in engineering and scientific situations. Many times, we need to find the average value of different scientific units such as weight, current, voltage in order to make good approximate estimations. For example, when boarding a small airplane, the average weight of passengers is taken in order to have an idea of the total weight that is entering the plane. This is needed to be computed because the plane can only handle a certain amount of weight in order to be able to safely go airborne. By computing averages, we can determine the total weight, to see if the airplane can manage all the passengers. Applications such as these is where calculating the mean has significant value.

Example Calculations
Calculate the mean of the numbers 3, 5, 7, 9, 11, and 17.


3+5+7+9+11+16/6= 7

Mean: 7

Calculate the mean of 7, 10, and 13.


7+10+13/3= 10

Mean: 10
