Abstract
In this study, we compared two newly proposed combined ratio estimators in stratified random sampling to the conventional combined stratified random estimator. These two newly proposed combined ratio estimators are in line with the conventional combined stratified random estimator. Four data sets called populations 1-4 were used to justify this research work. While, population 1 is based on the total monthly income and total monthly expenditure of 86 occupants of Kubwa Federal Housing Authority, Phase IV Estate, Abuja, Nigeria, Population 2 is based on the total monthly income and total monthly expenditure of 95 occupants of Gwarinpa II Estate, Abuja, Nigeria. Also, while population 3 is based on the total monthly income and total monthly savings of 86 occupants of Kubwa Federal Housing Authority, Phase IV Estate, Abuja, Nigeria, Population 4 is based on the total monthly income and total monthly savings of 95 occupants of Gwarinpa II Estate, Abuja, Nigeria and from the variance estimates obtained, it was observed that each of this newly proposed estimator was better and preferred based on the conditions attached to their preference.
