Thanks istealth Thanks - appreciate your help

Thanks And is the answer the same as I posted? Thanks Beamer

Hopefully someone will be able to help me. I am trying to derive the formula for variance of variance for a sample. This would be similar to variance of a sample mean which is sigma/sqrt(N). I know the variance of sample variance is sigma^2 * sqrt (2) / N, but I can't prove it...
