Function standard_deviation

pattern/metrics.py:565–570

Returns the standard deviation of the given list of values. Low standard deviation => values are close to the mean. High standard deviation => values are spread out over a large range.

    return sum((x-m)**2 for x in list) / (len(list)-int(sample) or 1)
