Hi, I wanted to join as a new developer of sympy, so I am looking through the code to get familiar with it. For /sympy/sympy/statistics/ distributions.py, the Sample class defines the variance to be: s.variance = sum([(x-mean)**2 for x in s]) / Integer(len(s))
But, this would be the biased estimator. My question is would/should this class use the unbiased estimator (replacing Integer(len(s)) with Integer(len(s)-1))?
