In sample survey, when data is collected, it is assumed that whatever isreported by respondent is correct. However, given the issues of prestige bias,personal respect, respondents self reported data often produces over-or-underestimated values from true value. This causes measurement error to be presentin sample values. In support of this study, we have considered some preciseclasses using dual under measurement error model. The expressions for the biasand the mean square errors of proposed classes have been derived and comparedwith, the mean per unit estimator, the Srivenkataramana 1980 estimator andSharma and Tailor 2010 estimator.
