In this paper, we derived an expression for the variance of treatment means in a split plot design with sampling using the variance components associated with the whole plot, split plot and sampling errors. The result from the data analysis shows that relative efficiency increases with increase in sample size while variance of treatment means decreases with increase in sample size.
