[Tutor] How to calculate Standard Deviation

[John M. Purser]

Jabbar,

You might want to look at Numerical python or Numarray:
http://www.pfdubois.com/numpy/html2/numpy.html

which has a function described as:
"td(m, axis = 0)

returns the unbiased estimate of the population standard deviation from a
sample along the axis'th dimension of m. (That is, the denominator for the
calculation is n-1, not n.)"

Hi guys,
Can any body guide me how to calculate Standard Deviation of a set of values
in each row of a table? Is there any built-in function to calculate it
directly or I have to formulate it by myself? I will appreciate your replys.
