Can anyone tell me how to compute pooled variance??
If we are given N (Population Size) Mean (X) and Variance for say 2 groups how can we compute the combined/pooled variance???????
Reply ASAP.
Thanks in advance.

firstly we find out pooled s.d or combined s.d then find out pooled variance.
as (s.d)^2 = variance.
