A clear clarification that can be used in court is only obtained after a laboratory examination ( DNA test , [ 12 ] measurement under a light microscope or a ...

In statistics, a sampling distribution or finite-sample distribution is the probability distribution of a given random-sample-based statistic.For an arbitrarily large number of samples where each sample, involving multiple observations (data points), is separately used to compute one value of a statistic (for example, the sample mean or sample variance) per sample, the sampling distribution is ...
