    ArcGIS gives inconsistent standard deviation values, and does not specify whether the value is
    the sample or population standard deviation. 

    For example, given values of 1,2,3

    field statistics returns a standard deviation of 0.816497

    summary statistics geoprocessing tool returns a standard deviation of 1.0
