Scilab has the '''stdev''' to compute the standard deviation of a sample so it is straightforward to have the standard deviation of a sample with a correction of the bias.
<lang>
T=[2,4,4,4,5,5,7,9];
stdev(T)*sqrt((length(T)-1)/length(T))
</lang>
{{out}}
<pre>
-->T=[2,4,4,4,5,5,7,9];
-->stdev(T)*sqrt((length(T)-1)/length(T))
ans = 2.
</pre>
