Abstract |
|
|
| The principal reason for stratification in the design of sample survey is to reduce the sample variance of the estimates. The main objective of stratification is to give a better cross section of the population so as to gain a higher degree of relative precision. Over the past number of years, many procedures have been developed to obtain optimum strata boundaries. After a brief discussion of fundamental theoretical contribution by Dalenius, a number of approximate rules which have been proposed as a result of the heavy computational work involved in solving the theoretical equations to obtain the optimum points of stratification were critically examined. In this manuscript, an attempt has been made to review and summarise the important works on some aspects of stratified sampling design, particularly the determination of optimum stratification points. |
