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> |
|||

<pre> |
|||
-->T=[2,4,4,4,5,5,7,9]; |
|||
-->stdev(T)*sqrt((length(T)-1)/length(T)) |
|||
ans = 2. |
