This tool calculates the mean deviation of your data set, helping you understand its variability.

## How to Use the Mean Deviation Calculator

To use this calculator, enter a comma-separated list of numerical values into the input field and click the “Calculate” button. The calculator will compute the mean and mean deviation of the numbers you have entered.

## Explanation

The Mean Deviation is a measure of how much the numbers in a set deviate from the mean (average) of the set. The steps to calculate the mean deviation are:

- Calculate the mean of the dataset.
- Compute the absolute deviation of each number from the mean.
- Take the mean of the absolute deviations.

## Limitations

This calculator does assume the input data is a simple comma-separated list of numbers. It does not support scientific notations, invalid characters, or complex data structures. Ensure the input follows the expected format to get accurate results.
