1. The probability distribution of a statistic obtained from a large number of samples drawn from a specific population
The sampling distribution of the mean shows how sample means vary around the true population mean.
A distribuição amostral da média mostra como as médias amostrais variam em torno da verdadeira média populacional.
2. In statistics, the distribution that describes the behavior of a sample statistic across all possible samples of a given size
Understanding the sampling distribution is crucial for hypothesis testing and confidence interval estimation.
Compreender a distribuição amostral é crucial para testes de hipóteses e estimação de intervalos de confiança.
