So to get Allan deviation from Allan variance, we just take the square root of every variance measure we calculated above. This sets the units back to ones that we can intuitively understand (i.e. the same units the sensor actually records - gravity equivalents).

In case you want to use the formula of the sample variance, you have to set the ddof argument within the var function to the value 1. Example 2: Variance of One Particular Column in pandas DataFrame. It is also possible to compute the variance for a column of a pandas DataFrame in Python.
