In this article, the maximum likelihood estimation method is used to estimate the unknown parameters of the exponentiated Pareto distribution based on ranked set sampling (RSS), median Ranked set sampling (MRSS) and simple random sample (SRS). Comparison between estimators of these techniques is made Through simulation study using some criteria: biases, mean square errors and the relative efficiency. At the same sample size, the study concluded that the estimators based on RSS and MRSS are more efficient than those obtained by the SRS.
