Abstract
This paper discusses three estimators for the population mean in simple random sampling i.e dual ratio estimator, dual product estimator and dual ratio-cum-product estimator. These estimators are biased estimators. The mean square error for each
estimator is evaluated and compared to obtain the most efficient one. This comparison shows that the dual ratio-cum-product estimator is more efficient than the dual ratio estimator and dual product estimator.
