Find the standard deviation of 2, 3, 5 and 6

Find the standard deviation of 2, 3, 5 and 6

Answer Details

$\begin{array}{ccc}x& x-\overline{x}& (x-\overline{x}{)}^2\\ 2& -2& 4\\ 3& -1& 1\\ 5& 1& 1\\ 6& 2& 4\\ \sum x=16& & \sum (x-{\overline{x}}^2)=0\end{array}$
___________________________________
$\overline{x}$ = $\frac{\sum x}{N}$
= $\frac{16}{4}$
= 4
S = $\sqrt{\frac{(x-\overline{x}{)}^2}{N}}$
= $\sqrt{\frac{\left(10\right)}{4}}$
= $\sqrt{\frac{\left(5\right)}{2}}$
