The Fisher information amount of the scale parameter from Pareto distribution based on ranked set sampling (RSS) is studied.In order to give more insight into the performance of RSS compared with simple random sampling (SRS), the Fisher information amount based on RSS is compared with that based on SRS.The numerical results show that the RSS-based scale parameter carries more Fisher information than SRS-based ones.

Key words: ranked set sampling, Pareto distribution, Fisher information amount
