@ -122,7 +122,7 @@ When computing the standard deviation of :math:`X`, we have:
s^2=\frac{\sum_{i=0}^n (x_i-\overline{x})^2}{n}
In this case, the degree of freedom is :math:`n-1`. As the mean is already known, only :math:`n-1`
of the :math:`x_i` are allowed to vary. By knowing :math:`n-1` of the :math:`x_i`, we can deduce the last
