In this article we endeavor the issue of estimation of the entirety of mean and the difference in mean in mail reviews. This issue is directed for current occasion with regards to group examining (cluster sampling) over inspecting on two progressive occasions when there is non-response (i) on one and two (both) occasions, (ii) just on the first occasion and (iii) just on the second occasion. An examination between variances of the estimates is discussed. The outcomes got are exhibited with the assistance of simulation study.
