摘要：In sample s urveys, it is usual to make use of auxiliary information to increase theprecision of estimators. A general class of estimators is suggested to estimate the population meanfor the variable under study in two stage sampling scheme. Some special cases of this class ofestimators are considered and are compared by using a data set.It turns out that the newly suggested estimators dominate all other well knownestimators in terms of mean square error. Finally it is shown, how to extend the class of estimatorsif multi auxiliary variables are available in the cases of two stage sampling scheme
