Fw: Standard Deviation

["Peter Gibson" <Peter_Gibson@xxxxxxxxxxxxxx>]

after a little more thought I came up with a brute force solution for
calculating the standard deviation of a number of variables.  I just stuffed
them in an array and calculated as follows:

For value1=1 to 7 begin
     value2=value2+SDArray[value1];
end;
value2=value2/7;
for value1=1 to 7 begin
     value3=value3+Square(SDArray[value1]-value2);
end;
SD=SquareRoot(value3,6);

That should do the trick but I'd still be curious if anyone else has a
better method.
