Already answered this qstn.
Again Reposting it for the ease:
It is very difficult to calculate the standard deviation directly and easily therfore the exact dats is necessary to go wwith the further calcukations.
Formulae:
sigma = root(\sum(xi – x’)^2) for i= 1 to i =N.
where x’ is the average mean.
