Enter a list of numbers to calculate the average (mean), median, sum, lowest value, and highest value.
You can enter whole numbers or decimal numbers. Separate values using commas, spaces, or line breaks. The calculation is performed directly in your browser.
Here is a statistical summary of the numbers you entered.
The values below are shown in the same order in which they were entered. They are not changed by the median calculation.
In everyday use, "average" usually refers to the arithmetic mean. It is calculated by adding all the values in a data set and dividing the total by the number of values.
For example, if five test scores are 75, 82, 68, 91, and 84, their sum is 400. Because there are five scores, the average is 400 ÷ 5 = 80.
The median is the middle value after a collection of numbers has been arranged from smallest to largest.
If there is an odd number of values, the median is the single middle value. If there is an even number of values, the median is the average of the two middle values.
Both the average and median describe the center of a group of numbers, but they respond differently to unusually high or low values.
| Statistic | How It Is Calculated | Useful When |
|---|---|---|
| Average / Mean | Sum divided by number of values | You want the overall numerical average. |
| Median | Middle value after sorting | You want a measure that is less affected by extreme values. |
| Lowest | Smallest value in the data set | You need the minimum result. |
| Highest | Largest value in the data set | You need the maximum result. |
The average uses every value in the calculation, so an unusually large or unusually small number can affect it significantly.
The median depends primarily on the position of values after sorting. This makes it less sensitive to extreme values.
In this example, the value 100 pulls the average upward, while the median remains closer to the values in the middle of the data set.
In addition to the average, this calculator provides several useful summary values:
Your calculations are performed directly in your web browser. The numbers you enter do not need to be sent to a Resouria server for processing.
This makes the calculator convenient for ordinary calculations and reduces the need to transmit the entered data over the internet. If you use a shared computer, however, avoid entering information that you do not want other users of that device to see.
