How to Use the Average Deviation Calculator

To use this calculator, simply enter a list of numbers separated by commas, without spaces or any other characters, in the input field above and then click on the “Calculate” button. The result will be displayed in the “Result” field.

How It Works

The calculator first takes the input values and creates an array from the numbers provided by splitting the string on commas. It then calculates the mean (average) of these numbers. Subsequently, it computes the deviation of each number from the mean (the absolute difference between each number and the mean) and finally calculates the average of these deviations giving us the average deviation of the data set.


This average deviation calculator expects numbers separated by commas and will not function correctly if any other characters are included. Non-numeric values or empty input will result in an incorrect calculation. Ensure that you enter valid numerical data for accurate calculations.
