I have a vector that contains:

v = 0.5677    0.4792    0.4844    0.4870    0.5104    0.4870    0.4792 
0.4974    0.4688    0.4870

Now I would like to know how much this data varies. I was thinking:

a = max(v) - min(v)

But if just one sample is very different (like 10.0) then the above 
procedure will not give a realistic result.

I have also tried to use the matlab var function:

&gt;&gt; var(v)

ans =

  7.7977e-004

But 0.0007 is not where most of the data belongs. Is there better approach 
to this problem?
