ESTIMATION OF POPULATION VARIANCE USING QUARTILES IN ABSENCE AND PRESENCE OF NON-RESPONSE

In this study, we have addressed the issue of estimation of population variance utilizing  quartiles and some of their functions of an auxiliary variable in absence and presence of non-response.  A class of ratio type estimators have been suggested with their MSEs’ in simple random sampling. The  suggested estimators have been compared with the reviewed estimators. Further, an empirical illustration  is carried out to support the theoretical findings.
