1. In statistics, the probability distribution of a sample statistic calculated from a finite population or a finite number of observations, as opposed to an asymptotic distribution.
The finite sample distribution of the test statistic differs from its asymptotic approximation.
A distribuição de amostra finita da estatística de teste difere de sua aproximação assintótica.
2. The actual sampling distribution when the sample size is fixed and known, without relying on large-sample approximations.
For small samples, researchers must use finite sample distribution theory rather than normal approximations.
Para amostras pequenas, os pesquisadores devem usar a teoria de distribuição de amostra finita em vez de aproximações normais.
