RANKED SET SAMPLING FOR ENVIRONMENTAL STUDIES

Here the fact that Ranked Set Sampling (RSS) procedures were initially developed for environmental studies is emphasized. These procedures envisage ranking a large number of observations (in small groups) and actually measuring only a few of them. The basic procedure to estimate the mean and its higher efficiency over the SRS procedure is demonstrated. Then we discuss the modification to be carried out for developing nonparametric confidence intervals for quantiles. Lastly we discuss some tests for perfect judgment ranking of observations which should be used as preliminary procedures before the RSS methodology is adopted.
