Keywords:
Ratio Estimators, Simple Random Sampling, Auxiliary Attribute, Mean Square Error, Efficiency.Abstract
In this paper, some ratio estimators for the population mean using known coefficient of skewness based on auxiliary attribute have been proposed and these have been developed by combining ratio estimators for estimating population mean of variate of study using the procedure given in Kadilar and Cingi (2006). The mean square error (MSE) equations for suggested estimators have been derived and it has been concluded that the suggested estimators always perform better than the ratio estimators, given in Sections 1 and 2. The results are also supported by the three original datasets.
