Abstract: We consider the problem of estimating finite population variance of a study character when information on an auxiliary character is available. We define ratio- and difference-type estimators and obtain the mean-squared error of them approximately. Using a numerical study, we compare the performances of the proposed estimators with some existing variance estimators.
