The program SimSam for simulating samples

SimSam is a program to simulate samples from finite populations. By repeating the selection of the sample a large number of times, and computing an estimate for the population mean for each sample, the distribution of the estimate can be portrayed on the screen. By taking a look at this distribution, it becomes clear how well an estimation procedure is able to estimate the population mean.
