Abstract |
|
|
| In this paper, some ratio-type estimators for finite population variance have been proposed using known values of the parameters of an auxiliary variable such as quartiles and their functions under simple random sampling. The suggested estimator has been compared with the usual unbiased estimator of population variance under large sample approximation. An empirical study has been also conducted to judge the merits of the proposed estimator over other existing ratio estimators for the population variance. |
