... There are two things to notice. First, the mean of all possible samples selected with replacement (i.e., 10.1) is equal to the mean of all samples selected without replacement, and both sample means are equal to the population mean. Thus, the sample mean on average remains an unbiased estimator of ...

German tank problem



In the statistical theory of estimation, the problem of estimating the maximum of a discrete uniform distribution from sampling without replacement is known in English as the German tank problem, due to its application in World War II to the estimation of the number of German tanks.The analyses illustrate the difference between frequentist inference and Bayesian inference.Estimating the population maximum based on a single sample yields divergent results, while the estimation based on multiple samples is an instructive practical estimation question whose answer is simple but not obvious.
