The present study discuss the problem of estimating the finite populationmean using auxiliary attribute in stratified random sampling. In this papertaking the advantage of point bi-serial correlation between the study variableand auxiliary attribute, we have improved the estimation of population mean instratified random sampling. The expressions for Bias and Mean square error havebeen derived under stratified random sampling. In addition, an empirical studyhas been carried out to examine the merits of the proposed estimator over theexisting estimators.
