private static double computedStdDev(double sumSquared, double sum, long n)
{
  double average = sum / n;
  double variance = (sumSquared - 2 * sum * average + average * average * n) / n;
  // variance might be negative because of numeric inaccuracy, therefore we need to use max
  return sqrt(max(variance, 0d));
}

  double variance = (sumSquared - 2 * sum * average) / totalWeight + average * average;
  // variance might be negative because of numeric inaccuracy, therefore we need to use max
  return sqrt(max(variance, 0d));
