Abstract
This paper measures the effect of random non-response (I) on the study as well as the auxiliary variables [Situation 1], and (II) on the study variable only [Situation 2] by considering a class of estimators for population mean. it has been shown that the class of estimators defined under situation 1 is more efficient as well as more non-response robust than the class of estimators defined under situation 2. This study also generalized the work of Tracy and Osahan (1994).
