In this artikel the combination of ratio estimators and ratio regression in simple random sampling using median and coefficient of skewness are discussed, which is a review and an expansion from the article J. Subramani ...

The ratio estimators studied here are ratio estimators for population mean of simple random sampling by using information of correlation coefficient, second quartile, quartile deviation and decile mean. Each estimator ...

In this article we study the ratio estimator, regression estimator and ratio regression estimator using two auxiliary variables in simple random sampling, which is a review from parts of an article Abu-Dayyeh ...

This paper discusses three ratio estimators for population variance in simple random sampling using quartiles of the auxiliary variable given by Subramani and Kumarapandiyan [International Journal of Statistics and ...

This paper studies three ratio estimators in simple random sampling by using the second decile, fifth decile and the eighth decile. This three ratio estimators are biased estimators. Their mean square errors are compared ...

In this article we review three estimators for the population variance in simple random sampling using regression coefficient and two auxiliary information. They were proposed by Gupta and Shabbir [2] which is a review of ...
