It turns out to be useful in nding the distribution of an order statistic. While the sample mean and sample variance can be very useful quantities in many situations, they are not always the most appropriate statistics for a particular research question. In the german tank problem, we were interested in estimating the total number of tanks the. If we want to make inferences about a parameter, we need to know the distribution of the statistic/estimator we"re using. Last semester, we derived the distributions of the sample mean and sample variance, as well as the distributions of some functions of these statistics.
