1. A branch of statistics that assumes data follows a specific probability distribution and relies on population parameters to make inferences about populations
Parametric statistics requires that the data be normally distributed to apply t-tests and ANOVA.
A estatística paramétrica requer que os dados sejam distribuídos normalmente para aplicar testes t e ANOVA.
2. Statistical methods that make assumptions about the parameters of the underlying probability distribution of the data
When using parametric statistics, we assume known variance and normal distribution of the sample.
Ao usar estatística paramétrica, assumimos variância conhecida e distribuição normal da amostra.
