This Median Calculator calculates the median value of the numbers entered into the form field.

The median of a set of numbers is the middle most term out of a group of terms once the numbers are arranged in ascending order from least to greatest. If the group of numbers is an odd number, the median value is simply the middle term out of the groups of numbers (again once the numbers are in ascending numeric order). If the group of numbers is an even number, then the meidan value is simply the average of the 2 middle most terms.

For example, let's say we have an odd set of numbers, 10, 9, 7. Once we arrange these numbers in ascending order, we get 7, 9, 10. Thus, the median number is simply the middle term, which is 9. 9 is the median.

Now let's say we have an even set of numbers, 12, 3, 17, 8. When we arrange these terms in ascending order, we get 3, 8, 12, 17. Since there is no direct middle term, we take the 2 most middle terms, 8, 12, and add them together and find their average. 8+12/2= 10. Therefore, the median value of this group of terms is 10.

To use this calculator, a user just enters in the set of numbers which he wants to compute the median 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 median value will be calculated and displayed.

The units which the median 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 median value can be significant in engineering and scientific situations where it is important to find the midrange. Being that the median is the value of a number of values in ascending order, it can give a good midrange approximation in many engineering applications.

Example Calculations
Calculate the median of the numbers 17, 5, 11, 9, 7, 3

Calculation:

Ascending order: 3, 5, 7, 9, 11, and 17.

Median: 7+9/2= 8

Calculate the median of 14, 5, 9.

Calculation:

Ascending order: 5, 9, 14

Median: 9
