More about the Mean Squared Deviation so you can better understand the results provided by this calculator. For a sample of data, the Mean Squared Deviation, which is computed as the average of squared deviations from the mean, corresponds to a measure of deviation associated to a dataset. Mathematically, we get that the Mean Squared Deviation is computed using the following formula:

$\text{Mean Square Deviation Calculator} = \displaystyle \sum_{i=1}^n \left(\bar x - x_i\right)^2$

A similar measure you would like to consider to complement the results obtained with the mean squared deviation is the mean absolute deviation .
