Calculation  of Standard Deviation - Discrete Series

  There are three methods for  calculating  standard  deviation  in discrete series":

a.Actual Mean Methods: It include the following  steps

1.Calculate  the mean  of the  series.

2.Find deviations for various items from the  mean i ,e, X- s

3.Square  the deviations  d2 and multiply by the respective frequencies(f) we get fd2.

4. Total the product ( ∑fd2). The  apply  the formula.

                                           = √∑fd2/ ∑f
