- d — Data values
Worked example
With data values = 4,8,6,5,3,2,8,9,2,5, the calculator gives mean absolute deviation ≈ 2.04.
Frequently asked questions
What is the mean absolute deviation calculator used for?
Find the average distance of values from their mean. It helps with questions such as “mean absolute deviation”, “average deviation from mean”, “MAD of data”.
What is the formula for the mean absolute deviation calculation?
Mean absolute deviation = mean(d.map(function(v){return abs(v-mean(d))})). Here d is data values.
What inputs do I need for the mean absolute deviation calculator?
You need data values. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the mean absolute deviation calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the mean absolute deviation result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
