Additive standard deviation
WebNo. Variances are additive, so: v a r ( ∑ i = 1 n x i) = ∑ i = 1 n v a r ( x i) = n ⋅ v a r ( x) Which means: s t d ( ∑ i = 1 n x i) = n ⋅ s t d ( x) Share Cite Follow answered Nov 4, 2012 at 22:16 pedrosorio 868 6 7 Show 1 more comment You must log in to answer this question.
