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.

${\tilde{\mu }}_3=\frac{{\sum }_i^N{\left(X_i-\bar{X}\right)}^3}{(N-1){\sigma }^3}$

Another Formula $\text{skewness}=\frac{3(\overline{y}-m)}{\sigma }$ where $m$ is the median
