Answer
$2,2,2.739$
Work Step by Step
We are given that $x=-1,0,2,3,6$
Now, we will find.
$\bf{Mean}$$=\dfrac{-1+2+0+3+6}{5}=2$
$\bf{Median}$$=[\dfrac{(5+1)}{2}]^{th}=\text{3rd term}=2$
Therefore, $\bf{Standard \space Deviation}$$=\dfrac{(-1-2)^2+(2-2)^2+(0-2)^2+(3-2)^2+(6-2)^2}{5-1} \\=\dfrac{9+0+4+1+16}{4}\\=\dfrac{30}{4}\\=2.739$
