standard deviation
     
         sd a measure of the range of values in a set of
        numbers.  standard deviation is a statistic used as a measure
        of the dispersion or variation in a distribution, equal to the
        square root of the arithmetic mean of the squares of the
        deviations from the arithmetic mean.
     
        the standard deviation of a random variable or list of numbers
        the lowercase greek sigma is the square of the variance.
        the standard deviation of the list x1, x2, x3...xn is given by
        the formula:
     
         sigma = sqrtx1-avgx^2 + x1-avgx^2 +
                      ...  + xnavgx^2/n
     
        the formula is used when all of the values in the population
        are known.  if the values x1...xn are a random sample chosen
        from the population, then the sample standard deviation is
        calculated with same formula, except that n-1 is used as the
        denominator.
