Abstract
Work discusses three sampling designs: simple random sampling, systematic random sampling and stratified random sampling. GREG estimation theory was examined as well. The goal of the research was to compare the above mentioned sampling designs by using the simulation experiments to determine the sampling design that gives more accurate estimates of certain population parameters. To carry out simulation experiments sampling data were generated and programs processing these data were developed. These programs were run several times with different number of samples and different sample sizes. Simulation experiments were carried out using R program. Simulation exper...
