Variance/Standard Deviation.

In[79]:=

Var = ∫_lowsupport^highsupport (x - ExpValue)^2 f[x, ν] x   

Out[79]=

10/9

In[80]:=

N[Var^(1/2)]

Out[80]=

1.05409

In[81]:=

(* Alternatively *)∫_lowsupport^highsupport x^2 f[x, ν] x - ExpValue^2

Out[81]=

10/9

In[82]:=

                   StdDev = Var^(1/2)

Out[82]=

10^(1/2)/3
