Mar 17, 2016 · 3 Answers. By expanding out the square, you can easily show that n ∑ i = 1(Xi − ˉX)2 = n ∑ i = 1X2i − nˉX2, using the fact that ∑ni = 1(Xi) = nˉX. So we need to calculate E[ n ∑ i = 1X2i] + E[nˉX2]. The first term, by the iid condition, is equal to nE[X2i]. Now note that Var(Xi) = E[X2i] − μ2, so E[X2i] = σ2 + μ2.
