摘要：
A double sampling estimator and its generalized estimator representing a class of estimators using auxiliary information in the form of mean and variance both are proposed for the estimation of population variance. Bias and Mean Square Error are found and the properties of the estimators are studied. A comparative study with the estimators available in the literature is also carried out and it is shown that the proposed estimator and its generalized estimator are more efficient. The results are supported with the help of a numerical example.
