1. The probability distribution of a statistic calculated from a sample of finite size, as opposed to the asymptotic distribution that would result from an infinitely large sample.
The finite-sample distribution of the test statistic differs from its asymptotic normal approximation when the sample size is small.
A distribuição de amostra finita da estatística de teste difere de sua aproximação normal assintótica quando o tamanho da amostra é pequeno.
2. In statistics and econometrics, the actual distribution of an estimator or test statistic for a specific, fixed sample size rather than in the limit as the sample size approaches infinity.
Researchers must consider the finite-sample distribution when conducting hypothesis tests with small datasets.
Os pesquisadores devem considerar a distribuição de amostra finita ao conduzir testes de hipóteses com conjuntos de dados pequenos.
