{begin{equation/

T_{variance}=(n) = /frac{/sqrt/sigma_{s_{n}^[intra}}^2+{/sigma_{S_{n}^{inter}}^2}}}

{l/{left/l/l /bar s_n^{intra}- / bar s_n^{inter}/right 

{end{equation/

 \begin{equation}
T_{variance} (n) = \frac {\sqrt {\sigma_{S_n^{Intra}}^2 + \sigma_{S_n^{Intra}}^2}} {\| \bar{S}_n^{Intra} - \bar{S}_n^{Intra} \| }
\end{equation}

$T_{varience}(n)=\frac{\sqrt{\sigma _{S_{n}^{Intra}}^{2}+\sigma
_{S_{n}^{Inter}}^{2}}}{\left\Vert \overline{S}_{n}^{Intra}-\overline{S}%
_{n}^{Inter}\right\Vert }$

Or

\begin{equation*}
T_{varience}(n)=\frac{\sqrt{\sigma _{S_{n}^{Intra}}^{2}+\sigma
_{S_{n}^{Inter}}^{2}}}{\left\Vert \overline{S}_{n}^{Intra}-\overline{S}%
_{n}^{Inter}\right\Vert }
\end{equation*}
