valid approach     (M1)

eg$\,\,\,\,\,$${x_{\max }} - {x_{\min }}$, interval 2 to 11

${\text{range}} = 9$          A1     N2

recognizing that variance is ${({\text{sd}})^2}$     (M1)

eg$\,\,\,\,\,$$\operatorname{var}  = {\sigma ^2},{\text{ 2.9060}}{{\text{5}}^2},{\text{ }}{2.92562^2}$

${\sigma ^2} = 8.44515$

${\sigma ^2} = 8.45$     A1     N2
