Talk:Coskewness

Article incorrectly conflates 0 skewness with symmetry
This article says "It follows that the sum of two random variables can be asymmetric (SX+Y ≠ 0) even if both random variables are symmetric in isolation SX = 0 and SY = 0)."

The skewness coefficent being 0 does *not* imply symmetry.

This widely held misconception should be reproduced in Wikipedia articles. — Preceding unsigned comment added by Glenbarnett (talk • contribs) 08:12, 17 August 2015 (UTC)
