摘要：In this paper, we discuss estimating the normal population parameters using moving ranked set sampling (MRSS) scheme. We derive new estimators and obtain confidence intervals for these parameters. Also, we conduct a simulation study to asses the performance and efficiency of the proposed estimators compared with their competitors based on simple random samples (SRS). Results indicate that the proposed population mean estimators are more efficient than those obtained using SRS. A grassland biodiversity example in central Europe is used to illustrate the usefulness of the proposed method in the field of Ecology.
