# Skewness

Skewness is **a measure of symmetry, or more precisely, the lack of symmetry**. It measures bias towards left or right side.

There is a formula for this, but I won’t copy paste until I learn about this.

$μ~ _{3}=(N−1)σ_{3}∑_{i}(X_{i}−Xˉ)_{3} $

Another Formula $skewness=σ3(y −m) $ where $m$ is the median
