There are many ratio and product type mean estimators proposed in different sampling schemes in sampling literature. However, a large number of them are more efficient than the others in certain circumstances, depending on the structure of the data used. Determining the theoretical efficiency conditions of the estimators significantly facilitates the work of practitioners and provides appropriate help in identifying the most suitable estimators according to the structure of the data set they

In this study, the performance of many ratio and product type mean estimators is compared over their Bias, the Mean Square Error values and specific efficiency conditions are determined. In addition, a discussion is held on which of the mean estimator achieves to obtain the best estimation over a real data set on the table olive production taken from the records of the Turkish Statistical Institute for 2010.
